A material point begins to move along the straight line with constant acceleration from its resting state. During the fifth second of its motion, the speed of the material point has increased by $$4~m/s$$. What distance did the material point travel during the third second? Give your answer in meters accurate to the whole. A material point begins to move along the straight line with constant acceleration from its resting state.

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?
