In the blizzard of ’88, a rancher was forced to drop hay bales from an airplane to feed her cattle. The plane flew horizontally at 160 km/hr and dropped the bales from a height of 80 m above the flat range, (a) She wanted the bales of hay to land 30 m behind the cattle so as to not hit them. Where should she push the bales out of the airplane? (b) To not hit the cattle, what is the largest time error she could make while pushing the bales out of the airplane? Ignore air resistance.
A skier leaves the end of a horizontal ski jump at 22.0 m/s and falls through a vertical distance of 3.20 m before landing. Neglecting air resistance, (a) how long does it take the skier to reach the ground? (b) How far horizontally docs the skier travel in the air before landing? (Sec Section 3.4.)
To test the quality of a tennis ball, you drop it onto the floor from a height of 4.00 m. It rebounds to a height of 2.00 m. If the ball is in contact with the floor for 12.0 ms, (a) what is the magnitude of its average acceleration during that contact and (b) is the average acceleration up or down?
Suppose a chinook salmon needs to jump a waterfallthat is 1.50 m high. If the fish starts from a distance 1.00 mfrom the base of the ledge over which the waterfall flows,(a) find the x - and y - components of the initial velocity the salmon would need to just reach the ledge at the top of itstrajectory. (b) Can the fish make this jump? (Note that a chinooksalmon can jump out of the water with an initial speedof 6.26 m/s.)
A placekicker must kick a football from a point 36.0 m(about 40 yards) from the goal. Half the crowd hopes the ballwill clear the crossbar, which is 3.05 m high. When kicked, theball leaves the ground with a speed of 20.0 m/s at an angle of53.0° to the horizontal. (a) By how much does the ball clear orfall short of clearing the crossbar? (b) Does the ball approachthe crossbar while still rising or while falling?
First, you will investigate purely vertical motion. The kinematics equation for vertical motion (ignoring air resistance) is given by y(t)=y0+v0t−(1/2)gt2, where y0=0 is the initial position, v0 the initial speed, and g is the acceleration due to gravity. Drag the cannon downwards so it is at ground level, or 0 m (which represents the initial height of the object), then fire the pumpkin straight upward (at an angle of 90∘) with an initial speed of 14 m/s. How long does it take for the pumpkin to hit the ground?
A test rocket is launched by accelerating it along a 200.0m incline at 1.85m/s2 starting from rest at point A. The incline rises at 35.0o above the horizontal, and at the instant the rocket leaves it, it's engines turn off, and it is subject only to gravity (air resistance can be ignored) a) find the maximum height above the ground that the rocket reaches in m b) find the greatest horizontal range of the rocketbeyond point A
A car is moving at 18.00[m/s], and comes to a stop in 3.45[s], due to friction acting on the car. Assuming the acceleration is constant, what is the magnitude of the acceleration experienced by the car? Express your answer in m/s2.
The cheetah can reach a top speed of 114 km/h (71 mi/h).While chasing its prey in a short sprint, a cheetah starts fromrest and runs 45 m in a straight line, reaching a final speed of 72km/h. (a) Determine the cheetah’s average acceleration duringthe short sprint, and (b) find its displacement at t = 3.5 s.

A woodpecker’s brain is specially protected from large decelerations by tendon-like attachments inside the skull. While pecking on a tree, the woodpecker’s head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. (a) Find the acceleration in m/s^2 and in multiples of g (g=9.80m/s^2). (b) Calculate the stopping time.
An initially stationary hovercraft sits on a large lake. Whena whistle blows the hovercraft accelerates due north at a rate of1.2 m s−2for 10 s, does not accelerate at all for the next 10 s, andthen accelerates at a rate of 0.6 m s−2 due east for another 10 s. Thehovercraft then coasts for another 10 s without any acceleration.(a) What is the velocity of the hovercraft 40 s after the whistleblows?(b) What is the displacement of the hovercraft 40 s after thewhistle blows?
