You drop a ball from a window on an upper floor of a building and ii is caught by a friend on the ground when the ball is moving with speed vf. You now repeat the drop, but you have a friend on the street below throw another ball upward at speed vf exactly at the same time that you drop your ball from the window. The two balls are initially separated by 28.7 m. (a) At what time do they pass each other? (b) At what location do they pass each other relative the window?
Two students are on a balcony 18.6 m above the street. One student throws a ball (ball 1) vertically downward at 15.1 m/s; at the same instant, the other student throws a ball (ball 2) vertically upward at the same speed. The second ball just misses the balcony on the way down. (a) What is the difference in the two ball's time in the air? (s)(b) What is the velocity of each ball as it strikes the ground? ball 1 magnitude (m/s) direction ---Select--- upward downward ball 2 magnitude (m/s) direction ---Select--- upward downward (c) How far apart are the balls 0.900 s after they are thrown? (m)
A ball is thrown straight up from the ground with speed v0. At the same instant, a second ball is dropped from rest from a height H, directly above the point where the first ball was thrown upward. There is no air resistance. Find the time at which the two balls collide. Find the value of H in terms of vo and g so that at the instant when the balls collide, the first ball is at the highest point of its motion.
A juggler performs in a room whose ceiling is 4.62 m above the level of his hands. He throws a ball upward with an upward speed of v 0 so that it just reaches the ceiling. At the instant when the first ball is at ceiling, the juggler throws a second ball upward with 4 v 0 /3 velocity. At what distance above the juggler’s hand do they pass each other?

Hunter kicks a soccer ball with an initial velocity of 25 m/s at 30o above the horizontal. Which of the following describes the horizontal component of the ball’s velocity? a It is zero b It is 25 m/s c It changes uniformly d It remains constant during the ball’s flight
An object is thrown vertically upward. Which of the following is true? Select one: a. It’s velocity changes non-uniformly. b. The speed on the returning to its starting point is the same as its initial speed. c. The maximum height is independent of the initial velocity. d. The travel time upward is slightly greater than the travel time downward.
A red train traveling at 72 km/h and a green train traveling at 144 km/h are headed toward each other on a straight, level track. When they are 950 m apart, each engineer sees the other's train and applies the breaks. The brakes slow each train at the rate of 1.0 m/s^2. Is there a collision? If so, what is the speed of the red train and the speed of the green train? If not, what is the separation between the trains when they stop?
A ball is dropped from the top of a tall building. At the same instant, a second ball is thrown upward from the ground level. When the two balls pass one another, one on the way up, the other on the way down, compare the magnitudes of their acceleration:(a) The acceleration of the dropped ball is greater.(b) The acceleration of the ball thrown upward is greater.(c) The acceleration of both balls is the same.(d) The acceleration changes during the motion, so youcannot predict the exact value when the two balls pass each other.(e) The accelerations are in opposite directions.

A projectile is launched from ground level to the top of a cliff which is 195 mm away and 135 mm high If the projectile lands on top of the cliff 9.4 ss after it is fired, find the initial velocity of the projectile (magnitude and direction). Neglect air resistance. Express your answer to two significant figures and include the appropriate units.
