5. What is the speed of the ball at ground level just after the throw? (8.85...
ball is thrown at a 60.0° angle above the horizontal across level ground. It is throw rom a height of 2.00 m above the ground with a speed of 16.0 m/s and experiences ppreciable air resistance. The time the ball remains in the air before striking the round is closest to
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
Playing shortstop, you pick up a ground ball and throw it to second base. The ball is thrown horizontally, with a speed of 26 m/s, directly toward point A (Figure 4-16). When the ball reaches the second baseman 0.40 s later, it is caught at point B. (Neglect air resistance.) Figure 4-16 (a) How far were you from the second baseman? m (b) What is the distance of vertical drop, AB? m
You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window... QUESTION 6 5 p You throw a ball vertically upward with an initial speed of 5 m/s from your dorm window. If the window is 10 m above the ground, find the time the ball is in flight. Give your answer with three significant figures and do not write the units. 5 p. QUESTION 7 Continuing with exercise 6, calculate the speed of...
You throw a ball straight upward with an initial speed of 12 m/s. What is the objects acceleration on the way up and on the way down? Calculate the maximum height the ball can reach. What is the total flight time of the ball?
Playing shortstop, you pick up a ground ball and throw it to second base. The ball is thrown horizontally, with a speed of 22m/s, directly toward point A (see the figure below). When the ball reaches the second baseman 0.45s later, it is caught at point B. (a) How far were you from the second baseman? (b) What is the distance of vertical drop, AB?
A ball is kicked at ground level with an initial velocity of 18 m/s m the horizontal direction and 11 m/s in the vertical direction. At what speed doer the hall hit the pound in m/s? For how long does the ball remain in the air in seconds? What maximum height is attained by the ball in meters?
A skater is moving with a speed of 3.3 m/s when she is at a height of 5 m above the ground on the frictionless track below. Neglect the effects of air resistance. Use the conservation of energy to determine the skater’s speed when she is 2 m above the ground on her way down the track. Use the conservation of energy to determine the skater’s speed when she is 2 m above the ground on her way back up...
Suppose you throw the 0.12-kg ball at this minimum speed. Your friend misses the catch. What is the ball's kinetic energy just before it hits the ground (2 s.f.)?
5. You throw a ball straight up from the ground level to a height of 10 ft. The ball falls down and hits the floor. It then bounces back to a height that is 8 ft and repeatedly bouncing up and down indefinitely, each time reaching a height four-fifths of the previous height. (a) When the ball hits the ground the first time, we call this the first hit. Find the height of the ball on the fifth hit. (b)...
