Standing on the roof of a 95-m tall building, a girl holds her hand past the edge and throws a ball straight up at 8 m/s. The ball rises, then falls and strikes the ground. Considering "up" to be the positive direction, find the ball's velocity v when it is 40 m above the ground. Remember to include a "-" sign if the velocity is negative. V = m/s
You throw a ball from the ground level at an angle of 0 = 40.0° above the horizontal. The ball lands on top of a cliff that has a height of h=10.0 m. When you release the ball, it is traveling at a speed of 25.0 m/s. How long does it take for the ball to land on top of the cliff?
Problem 7: A kid throws a water balloon at an angle of 62° towards his friend who is 8 m away. How fast would the water balloon leave the kid's hand so that it hits his friend at the same level it was thrown? Give your answer in m/s. Numeric : A numeric value is expected and not an expression. V =
