Bonita (mass of 60 kg) is stuck, motionless, on a frictionless frozen lake. The only thing she has on her is her iPhone 13 (mass of 175g). She throws her phone, knowing that she if she exerts a force on her phone, it will exert a force back on her (according to Newton's third law), sending her sailing her backwards and towards the safety of the lakeshore. She has a good arm, so she throws the iPhone with a speed of 30 m/s. With what speed does Bonita travel after throwing her phone and how much energy did Bonita expend throwing her phone (assuming 100% efficiency)?

A 53.8-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -2.10 m/s. Her hands are in contact with the wall for 0.550 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her). Note that this force has direction, which you should indicate with the sign of your answer. Number i Save for Later Units Attempts: 0 of 3 used Submit Answer
Four railroad cars, each of mass 2.50 x 104 kg, are coupled together and coasting along horizontal tracks at speed vi toward the south. A very strong but foolish movie actor, riding on the second car, uncouples the front car and gives it a big push, increasing its speed to 4.00 m/s southward. The remaining three cars continue moving south, now at 2.00 m/s. (a) Find the initial speed of the four cars. (b) By how much did the potential energy within the body of the actor change?
A 54.9-kg skater is standing at rest in front of a wall. By pushing against the wall she propels herself backward with a velocity of -1.93 m/s. Her hands are in contact with the wall for 1.09 s. Ignore friction and wind resistance. Find the average force she exerts on the wall (which has the same magnitude, but opposite direction, as the force that the wall applies to her).

b) Two students are watching an action film in which a car drives down a ramp onto the back of a moving lory. Both are moving at high speed, the car slightly faster than the lorry. One student complains that this is impossible because the car would not be able to stop before hitting the cab of the lorry. The car has mass 1250 kg and is moving at a speed of 28.0 m s¯ª. The lorry has mass 3500 kg and a speed of 25.5 m sª. The length of the flat back of the lorry allows a braking distance of 5.0 m. By considering both momentum and energy show that the stunt is possible, provided a minimum force of about 600 N slows the car down. You should support your explanations with calculations. Treat the situation as one in which two objects join together.
A 2.50 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 16.00. You shove a second box, of mass 1.50 kg, that's at the bottom of the ramp, so that it starts sliding up the ramp with a speed of 20.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.200. Where, from the bottom of the ramp, do they come to rest?
A barefoot field-goal kicker imparts a speed of 34 m/s to a football initially at rest. If the football has a mass of 0.31 kg and the time of contact with the ball is 0.019 s, what is the magnitude of the force exerted by the ball on the kicker’s foot?Answer in units of N.
Suppose you are navigating a spacecraft far from other objects. The mass of the spacecraft is 2.5 x 10" kg (about 25 tons). The rocket engines are shut off, and you're coasting along with a constant velocity of km/s. As you pass the location km you briefly fire side thruster rockets, so that your spacecraft experiences a net force of N for 18 s. The ejected gases have a mass that is small compared to the mass of the spacecraft. You then continue coasting with the rocket engines turned off. Where are you an hour later? (Think about what approximations or simplifying assumptions you made in your analysis. Also think about the choice of system: what are the surroundings that exert external forces on your system?)

There are two particles (1 and 2) that are moving around in space. The mass of particle 1 is 2.8 kg and the mass ofparticle 2 is 1.96 kg. The particles are isolated so that only the forces between the particles are significant. The forcethat 2 exerts on 1 is given by:~F21(t) = Fat ˆi + Fbt3 ˆjThe initial time is ti = 4.1 s and the final time is tf = 6.8 s.Use the following values for the parameters:Fa = -18.4 N/s , Fb = 11.2 N/s3, If the y component of the impulse from 1 on 2 is -5196 N s, what is the y component of the change in momentum forparticle 2?

There are two particles (1 and 2) that are moving around in space. The mass of particle 1 is 4.7 kg and the mass ofparticle 2 is 7.05 kg. The particles are isolated so that only the forces between the particles are significant.

Remember that the mass of particle 1 is 4.7 kg and that the mass of particle 2 is 7.05 kg. If both particles were atrest at the initial time, which particle will have the larger speed at the end of the time interval?
