If a car has a centripetal acceleration of 7m/s2 over a radius of 7m. How fast is it going a. 7 m/s
b 1 m/s
с o m/s
d 49 m/s

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?
