a ball rolls off a platform that is 13 meters above the ground. the ball's horizontal velocity as it leaves the platform is 5m/s. using the approximate value of g=10 m/s^2 how much time does it take for the ball to hit the ground?
A ball rolls off a platform that is 3 meters above the ground. The ball's horizontal velocity as it leaves the platform is 4.6 m/s. (a) How much time does it take for the ball to hit the ground? (See the example box, use g = 10 m/s2.) s (b) How far from the base of the platform does the ball hit the ground? m
A ball rolls off a shelf with a horizontal velocity of 6 m/s. (a) At what horizontal distance from the shelf does the ball land if it takes 0.6 s to reach the floor? (b) How far did it fall vertically? Use g = 10 m/s2
Back on Earth, a ball is thrown off a roof top with a horizontal velocity 7.4 m/s and a upward vertical velocity 3.9 m/s. It hits the ground 3.8 s later. What is the direction at which the ball hits the ground? Give the angle the velocity vector makes with vertical (straight down = 0o and horizontal = 90o). Use g = 9.8 m/s2 if needed and neglect air friction. Read carefully -- there are versions of this question with...
a ball rolls off a table top which is 2 m above the floor.Using d=1/2 g tsquare & g= 10m/s(square find how long does it take for the ball to hit the floor
a ball rolls off a table of height 1.3m at a speed of 6m/s horizontal. when it hits the ground, at what distance from the table does it hit?
A boy throws a ball off the top of a building with a speed of 5.0 m/s at an angle of 40.0° to the horizontal. If the ball strikes the ground 4.00 s later, how tall is the building? 6.
As shown, tennis ball A rolls off the top of a 10.0 m high wall, falls 4.00 m, and strikes another tennis ball, B, obliquely. (Figure 1) Before the collision, tennis ball Bhas a speed of 19.0 m/s as it moves upward. Each ball's mass is 57.0 g and the collision's coefficient of restitution is 0.630.(Figure 2) In the figure, ?1=30.0? and?1=20.0?. What is (vA)1, the velocity of tennis ball A, immediately before the collision?
Need help on part C! As shown, tennis ball A rolls off the top of a 10.0 m high wall, falls 4.00 m, and strikes another tennis ball, B, obliquely. (Figure 1) Before the collision, tennis ball B has a speed of 21.0 m/s as it moves upward. Each ball's mass is 57.0 g and the collision's coefficient of restitution is 0.730. (Figure 2) In the figure, a-30.0° and фі-20.0. What is (VA), , the velocity of tennis ball A,...
A ball rolls off the end of a horizontal table that is 4 meters off the ground. It is measured that the ball lands 3 meters away at the base. What speed did the ball roll off the end of the table? Sketch a picture to help. Show all work for full credit.
