A 2000 kg car is driving down the road at a speed of 30 m/s. It suddenly slams on its brakes and stops in 40 m. Assuming a constant acceleration, find: a) the force applied by the brakes on the car.
b) the time required to stop the car.

What is the relationship between the wavelength of a wave and it's energy?

Asystematic approach to problem solving is called a (an)

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
