PLEASE ANSWER ASAP AND PLEASE EXPLAI---if u dont explain, u get reported 1. A 1,200 kg car travels at 20 m/s. What is its momentum?
2. If the car in the previous question slows to a stop, what is its final momentum?
3. What is the change in momentum of the car in the previous questions?
4. If the car slows down in 5 seconds, what force does the car experience in braking?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
