A rubber ball (mass 0.25 kg) is dropped from a height of 1.5 m onto the floor.
Question:
A rubber ball (mass 0.25 kg) is dropped from a height of 1.5 m onto the floor. Just after bouncing from the floor, the ball has a speed of 4.0 m/s.
(a) What are the magnitude and direction of the impulse imparted by the floor to the ball?
(b) If the average force of the floor on the ball is 18 N, how long is the ball in contact with the floor? Ignore the force of gravity during the collision of the ball with the floor.
Step by Step Answer:
The impulse imparted by the floor is the change in the balls momentum and also the average force act...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
