A car is stopped for a traffic signal. When the light turns green, the car accelerates, increasing its speed from 0 to 5.80 m/s in 0.822 s. (a) What is the magnitude of the linear impulse experienced by a 68.0-kg passenger in the car during the time the car accelerates?

A(n) 0.56 kg softball is pitched at a speed of12 m/s. The batter hits it back directly at thepitcher at a speed of 28 m/s. The bat acts onthe ball for 0.017 s.What is the magnitude of the impulse imparted by the bat to the ball?Answer in units of N · s. What is the magnitude of the average forceexerted by the bat on the ball?Answer in units of N.

A particle with a mass of 1.90 kg is acted on by a force Fx acting in the x-direction. If the magnitude of the force varies in time as shown in the figure below, determine the following. (a) impulse of the force (in kg · m/s )  kg · m/s (b) final velocity of the particle (in m/s) if it is initially at rest  m/s (c) Find the final velocity of the particle (in m/s) if it is initially moving along the x-axis with a velocity of  −25.00 m/s.  m/s

A 0.12-kg ball is moving at 6 m/s when it is hit by a bat, causing it to reverse direction and have a speed of 14 m/s. What is the magnitude of the linear impulse experienced by the ball?

Suppose a child drives a bumper car head on into the side rail, which exerts a force of 4000 N on the car for 0.200 s. (a) What impulse is imparted by this force? (b) Find the final velocity of the bumper car if its initial velocity was 2.80 m/s and the car plus driver have a mass of 200 kg. You may neglect friction between the car and floor.

A handball of mass 0.200 kg, traveling horizontally at 25.0 m/s , strikes a wall and rebounds at 16.0 m/s . What is the magnitude of the impulse in(Ns) imparted on the ball?

A cruise ship with a mass of 1.43 ✕ 107 kg strikes a pier at a speed of 0.672 m/s. It comes to rest 5.94 m later, damaging the ship, the pier, and the tugboat captain's finances. Calculate the average force (in N) exerted on the pier using the concept of impulse. (Hint: First calculate the time it took to bring the ship to rest. Assume the ship moves in the positive direction. Indicate the direction with the sign of your answer.)
