A ball whose mass is 0.1 kg hits the floor with a speed of 6 m/s and rebounds upward with a speed of 4 m/s. If the ball was in contact with the floor for 1.5 ms (1.5multiply10-3 s), what was the average magnitude of the force exerted on the ball by the floor? Favg = N. Calculate the magnitude of the gravitational force that the Earth exerts on the ball: mg = N In a collision, for a brief time there are forces between the colliding objects that are much greater than external forces. Which of the following is true during the collision between the bouncing ball and the floor? The magnitude of the gravitational force exerted by the Earth is much greater than the magnitude of the force exerted by the floor. The magnitude of the force exerted by the floor is much greater than the magnitude of the gravitational force exerted by the Earth. The force exerted by the floor and the gravitational force exerted by the Earth are approximately equal in magnitude. Additional Materials

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
