A 95.0 kg football player is standing on a sheet of ice, i.e., there is negligible friction betweentheir feet and the ground. A 0.400 kg football is travelling horizontally at 12.0 m/s towardsthe football player just before they try to catch the ball. (a) If they successfully catch the ball,then how fast does the player and the ball move horizontally after it is caught? (b) If the ballhits the player and bounces off of their chest moving at 8.50 m/s in the opposite direction,then what is the speed of the player after the ball bounces off of their chest? (c) Include adiagram of each of the situations.

A young girl is riding a bicycle that has a total mass (including the kid) of 21.2 kg. The girl is moving at 5.99 m/s on a flat road when suddenly she slams on the brakes and skids to a stop in 8.22 meters. What was the magnitutde of the average force due to friction acting on the bicycle? Remeber, the magnitude of a force is always positive. Assume a constant friction force measured in Newtons and 3 significant digits in your answer.

A cat (mass of 3.63 kg) is on a sled (mass of 22.7 kg) which rests on an icy surface... so no friction. In front of this sled, there is another identical sled. The cat jumps from the first sled to the second AND immediately back to the first. Both jumps are made at a relative speed of 3.7 m/sec between the cat and the sled it is on. Calculate the final speeds of the two sleds!
While skydiving, a brilliant young physics student known affectionately as “Crazy Kaitlin”launches herself horizontally out of an airplane. The plane is flying steadily at 12,500 feetabove the Earth with a horizontal speed of 80 miles per hour. The total mass of Kaitlinand her gear is 75-kg. Assume g = -9.8 m/s2 While free-falling, Kaitlin engages in some aerial acrobatics. At one point, she finds herself rapidly spinning aboutan axis that runs from her head to her feet. If she wants to quickly decrease her rate of spin, the optimum way forher to this is:A) Cup her hands and claw wildly at the air B) Use counter-flagellation forcesC) Fold her arms tightly across her chest to decrease her moment of Inertia.D) Stretch her arms and legs as far outward as possible to increase her moment of Inertia
Your friend’s car has broken down, so you volunteer to push it with your own car to the nearestrepair shop, which is 2.0 km away. You carefully move your car so that the bumpers of the two carsare in contact. You then slowly accelerate to a speed of 2.5 m/s over the course of 1.0 min. The massof your friend’s car is 1.2 x 10 ^3 kg. Assume negligible friction.a) Calculate the normal force between the two bumpers. b) You then maintain a speed of 2.5 m/s. How long does it take you to reach the repair shop? c) Sketch the shape of a velocity time graph for the entire motion. d) Sketch the shape of a position time graph for the entire motion.
