SUMMARY
The impulse experienced by a tennis ball of mass 0.075 kg thrown at a wall with a speed of 15 m/s at a 45˚ angle can be calculated using the formula for impulse, which is the change in momentum. When the ball strikes the wall and rebounds at the same speed and angle, the impulse is equal to the change in velocity, which is a vector quantity. The direction of the velocity changes upon rebounding, resulting in a net impulse that can be quantified by considering the initial and final velocity vectors.
