Question: A rocket starts from rest and moves upward from the surface of the earth. For the first 10.0 s of its motion, the vertical acceleration

A rocket 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 a_y = (2.80 m/s³)t, 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?
