Suppose a child drives a bumper car head on into the side rail, which exerts a force of 2900 N on the car for 0.400 s. (Assume the initial velocity is in the positive direction.) (a)What impulse (in kg · m/s) is imparted by this force? (Indicate the direction with the sign of your answer.) kg · m/s (b)Find the final velocity (in m/s) of the bumper car if its initial velocity was 3.40 m/s and the car plus driver...

(10%) Problem 5: A ball with an initial velocity of 5.5 m/s and mass 2.5 kg moves at an angle 68° above the horizontal. The ball hits a vertical wall and bounces off so that it is moving 68° above the horizontal, moving in the opposite direction with the same speed. See the figure. е 4 What was the magnitude of the impulse delivered by the wall, in kilogram meters per second? Grade Summary Deductions Potential 100% E sin cos...
