A 50-kg object moving at a constant speed of 2 m/s to the right. The acceleration is . a 25 m/s^2 b 100 m/s^2 c 10 m/s^2 d 0 m/s^2

Do you agree with scientist’s prediction about the warming of alaska and other polar regions?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

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?
