Glaunch to impact a ball, initially at rest and 1 meter above ground, is launched upward with a 500n force acting for 0.02 seconds. the ball flies vertically upward to a maximum height and falls back, sinking into the soft ground a distance of 2.0 cm. calculate the velocity after 0.01 seconds of force is applied, the maximum height if the force terminated when the ball was 2m above ground, the velocity of impact when it reached the ground and the average force exerted by the ground on the ball.
