EXERCISES

1. A ball thrown horizontally from the top of a building 60m high strikes the ground at a point 45m from the building. Find: a) the time to reach the ground,;b) the initial speed of the ball; c) the velocity with which the ball strikes the ground

2. The horizontal and vertical components of the initial velocity of a ball are 4.5m / s and 3.6m / s respectively. Find a.) the initial velocity of the ball; b) the maximum height attained by the ball; and c) the displacement of the ball after 0.50s.

3. A marble leaves a 0.70-meter high table with an initial horizontal velocity of 3m / s Predict the time required for the pool ball to fall to the ground and the horizontal distance between the table's edge and the ball's landing location.

4. A soccer ball is kicked horizontally off a 20-meter high hill and lands a distance of 32 meters from the edge of the hill. Determine the initial horizontal velocity of the soccer ball.

5. A frog leaps horizontally from a 0.30 m high rock with a speed of 0.25 m / s How far from the base of the rock will she land?​
