A baseball player throws a ball straight up into the air. At a height of 2.4 m above the release point, the ball is moving at 1.9 m/s. What was the ball's initial speed in m/s? assume g = 9.8m/s2.

While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 5.89 m/s. The stone subsequently falls to the ground, which is 13.1 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s2 for the acceleration due to gravity. impact speed: How much time is the stone in the air? elapsed time: m/s

A diver runs off a platform with an initial horizontal velocity of 1.16 m/s in the positive x-direction. The platform is at a vertical height of 8.90 m above the water. How much time is the diver in the air before he strikes the water? O 1.77 s O 1.83 s O 3.21 s O 2.49 s O 1.35 s O 2.99 s

A ball is thrown down with an initial speed of 3.00 m/s from a height of 7.00 m above the ground. What is its speed right before it hits the ground, in m/s? Use g = 10.0 m/s2.

You are playing Hot Rod toy cars with your nephew and niece. Your nephew wanted to show off how fast he could launch a Hot Rod off the dining table 1.00 m above the floor by thrusting the car forward very fast but was no match against your niece who compensated slight lack of speed by pushing the car straight forward reaching a speed of 4.5 m/s at the edge of the table top when she let go of it. What was the magnitude of the final speed when it hit the floor?

You throw a 19.6-N rock vertically into the air from ground level. You observe that when it is 10.0 m above the ground, it is traveling at 20.0 m/s upward. What is the rock's initial speed as it left the ground? 32.4 m/s O 14.0 m/s 24.4 m/s 30.4 m/s O 17.3 m/s

A juggler throws a bowling pin straight up with an initial speed of 9.8 m/s from an initial height of 2.8 m. How much time elapses until the bowling pin returns to the same initial height?

A stone is thrown upward from a cliff at an angle of 35 degrees above the horizontal with a speed of 47 m/s. The stone hits the ground 5.0 s later. a) What is the x component of the stones initial velocity? v47.0m/s 35 O51.0m/s 041.0 m/s 38.5 m/s O270 m/s

Natalia throws a ball straight up. The ball leaves the her hand with a speed of 12.0 m/s when the hand is 1.70 m above the ground. How long is the ball in the air before it hits the ground? (She moves her hand out of the way.)

A ball is thrown straight down with an initial speed of 3.2 m/s from a height of 5.0 m. What is the position of the ball after 2.6 s, in meters? Use g = 10 m/s2.
