PLEASE HELP ME stuntman drives a car of mass 1125 kg east with a speed of 20 m/s.

I

a. If the car accelerates at a rate of -2 m/s?, how long will it take the car to go 50 m? (3

points)

b. The stuntman drives the car off an 80 m cliff while going 15 m/s. How long will it take the

car to land? (3 points)

c. How far horizontally from the cliff will the car land? (4 points)

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.
