Will give correct answer brainliest Answers:

A. they decrease the force of impact by providing a cushion during the impact. Smaller force = lower momentum

B. They decrease the force of impact by extending the time it takes to stop the driver and passenger. Longer time= Less force

C. It takes longer time for the velocity of the vehicle to decrease, therefore the force is less. Decrease in velocity = Less force.

D. when a cat rebounds it undergoes a greater change in velocity and the force is decreased. Lower force = greater change in velocity

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
