Answer:
ELASTIC collision
kinetic energy is conservate
Explanation:
As the ball bounces to the same height, it can be stated that the impact with the floor is ELASTIC.
As the floor does not move the conservation of the moment
po = pf
-mv1 = m v2
- v1 = v2
So the speed with which it descends is equal to the speed with which it rises
Therefore the kinetic energy of the ball before and after the collision is the same
The answer is 24N. Since the body is moving with constant velocity all the forces must balance (equal & opposite)
If the corner is rounded and is perfectly circular, then the acceleration is centripetal and is always directed toward the center.
