f 0.0124 J. The
object collides with a horizontal spring and compresses it by 0.800 m before it is brought to rest momentarily. What
is the spring constant of this spring? When the spring was compressed to 0.800 m, is the work done on the mass
m1 by the spring positive, zero, or negative?
tal force (F = 10 N) is applied to the block between A and B as shown in the figure. The kinetic energy of the block at A is 10 J and at B it is 20 J. How much work is done on the block by the force of friction between A and B?
