Question 5. A tennis ball that has a mass of 5.7 x 102 kg is travelling at a velocity of 35.0 m/s, south. when it collides with a concrete wall. The ball is in contact with the wall for a time of 4.0 x 10³ s. Immediately after the collision, the tennis ball is travelling at a velocity of 32 m/s, north. The magnitude of the average force exerted on the tennis ball by the wall, expressed in scientific notation, is a.b x 10te N. The values of a and b, the sign of the exponent, and the value of c are , and b + or - C

Expert Solution
Step 1
Acceleration is defined as the rate of change of velocity.
While solving the question we will consider the north direction as positive and the south as negative.
Givens:
- Initial velocity, u=-35.0 m/s (south).
- Final velocity, v=+32 m/s (north).
- Time, t=4.0x10-3 s.
- Mass of the ball, m=5.7x10-2 kg.
Require:
- Force, F=?
