A ball is shot up from a surface that is 20 m above the surface with an initial speed of 10 m/s.

1. What is the magnitude of the ball's displacement from the surface after 3.00 second has elapsed?

2. What max height will the ball reach from the surface of the earth?

3. How much time elapses between the throwing of the ball and its reaching to the earth?

4. Calculate the magnitude of the velocity of the ball after 3 seconds of throwing the ball.

A ball of mass m is shot straight up into the air by a spring-loaded launcher. Initially, the spring is compressed by a distance D. After the spring is released, the ball has a velocity v out of the launcher and finally reaches a maximum height H. Ignoring air resistance, which of the following statements are true? True False If the spring constant is doubled, the ball will max out at height 8H True False The initial potential energy of the spring...

A billiard ball is shot east at 2.80 m/s. A second, identical billiard ball is shot west at 1.20 m/s. The balls has a glancing collision, not a head-on-collision, deflecting the second ball by 90° and sending it north at 1.55 m/s. What is the angle that the velocity of the first ball makes after the collision, with respect to the east direction?

A shot putter threw a shot at an angle of 43o above the horizontal from a height of 2.0 m above the ground. The shot traveled 19.0 m horizontally from the launch position. (a) What was the initial speed of the shot when it left the shot putter’s hand? (b) How long was the shot in the air? {13.0 m/s, 2.0 s}

A diver of mass m drops from a board 6.00 m above the water's surface, as shown in the figure. Neglect air resistance. (a) Use conservation of mechanical energy to find his speed 3.00 m above the water's surface. (b) Find his speed as he hits the water. (c) Suppose the diver vaults off the springboard, leaving it with an initial speed of 3.68 m/s upward. Use energy conservation to find his speed when he strikes the water.

From the top of a cliff, at a height of 45 m above the sea surface, a projectile is launched at an initial speed of 100 m / s, at an elevation angle of 60 degrees. After the projectile touches the surface of the water, it enters the sea experiencing a constant horizontal retardation of -25 m / s ^ 2 and a constant vertical retardation of -3 m / s ^ 2, both for a time of 2 sec,...

One billiard ball is shot east at 1.8 m/s . A second, identical billiard ball is shot west at 1.1 m/s . The balls have a glancing collision, not a head-on collision, deflecting the second ball by 90∘ and sending it north at 1.49 m/s . a) What is the speed of the first ball after the collision? Express your answer to two significant figures and include the appropriate units. b) What is the direction of the first ball after...
