An arrow is shot from a height of 1.5 m toward a cliff ofheight H . It is shot with a velocity of 30 m/s at an angle of60º above the horizontal. It lands on the top edge of the cliff4.0 s later. (a) What is the height of the cliff? (b) What is themaximum height reached by the arrow along its trajectory? (c)What is the arrow’s impact speed just before hitting the cliff?
An eagle is flying horizontally at a height of 35 meters from the ground with a velocity of 7.6m/S and with a fish in claws. It drops fish. A) how much time passes since fish has hit the ground ? b) what are vx and vy of the fish when it hits the ground.?
A fastball pitcher can throw a baseball at a speed of 40 m/s (90 mi/h). (a) Assuming the pitcher can release the ball 16.7 m from home plate so the ball is moving horizontally, how long does it take the ball to reach home plate? (b) How far does the ball drop between the pitcher’s hand and home plate?
A stuntman sitting on a tree limb wishes to drop vertically onto a horse galloping under the tree. The constant speed of the horse is 10.0 m/s, and the man is initially 3.00 m above the level of the saddle. (a) What must be the horizontal distance between the saddleand the limb when the man makes his move? (b) Howlong is he in the air?
A fastball pitcher can throw a baseball at a speed of 40 m/s (90 mi/b). (a) Assuming the pitcher can release the ball 16.7 m from home plate so the ball is moving horizontally, how long does it take the ball to reach bone plate? (b) How far does the ball drop between the pitcher’s hand and home plate?
A rescue helicopter is hovering over a person whose boat has sunk. One of the rescuers throws a life preserver straight down to the victim with an initial velocity of 1.40 m/s and observes that it takes 1.8 s to reach the water. (a) List the knowns in this problem. (b) How high above the water was the preserver released? Note that the downdraft of the helicopter reduces the effects of air resistance on the falling life preserver, so that an acceleration equal to that of gravity is reasonable.

His speed remains constant as he goes counterclockwise around a level track with two nearly straight sections and two nearly semicircular sections, as shown in the aerial view of Figure CQ7.12. (a) What are the directions of his velocity at points A, B, and C? For each point, choose one: north, south, east, west, or nonexistent, (b) What are the directions of his acceleration at points A, B, and C? Figure CQ7.12

(a) What vertical velocity does he need to rise 0.750 m above the floor? (b) How far from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket?
