Tara Bball You are playing basketball with your friend. You dribble the ball and hits the floor. The speed of the ball right before it hits the floor is 0.50 [m/s] and dribbles back with a speed of 0.30 [m/s] right after it hits the floor. Assuming the collision is elastic and the upward direction being the positive direction. Given 0.70 (kg] as the ball's mass and 0.2 [s] as the time of contact, what is the average force that the floor exerts on the ball during the impact?

You are playing basketball with your friend. You dribble the ball and hits the floor. The speed of the ball right before it hits the floor is 0.50 [m/s] and dribbles back with a speed of 0.30 [m/s] right after it hits the floor. Assuming the collision is elastic and the
upward direction being the positive direction. Given 0.70 [kg] as the ball’s mass and 0.2 [s] as the time of contact, what is the average force that the floor exerts on the ball during the
impact?
A. −0.70 [N]
B. −2.8 [N]
C. 2.8 [N]
D. 0.70 [N]
