A toy doll and a toy robot are standing on a frictionless surface facing each other. The doll has a mass of 0.2 kg and the robot has a mass of 0.3 kg. The robot pushes on the
doll with a force of 0.3 N. The magnitude of the acceleration of the robot is:

A. Zero
B. 0.60 m/s2
C.1.0 m/s2
D.1.5m/s2

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?
