Mr. gewanter, whose mass is 60.0 kg, is doing a physics demonstration in the front of the classroom. a) how much gravitational force does he exert on 55.0-kg martha in the front row, 1.50 m away? b) how does this compare to what he exerts on 65.0-kg lester, 4.00 m away in the back row?

What is the measure of a change in an objects velocity?

The combining of light nuclei is called blank. blank as in not actually blank. you know what im tryin to say.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
