Question

A .500kg block attached to a spring with length .60m and force constant 40.0 N/m, is at rest with the back of the block at point A on a frictionless horizontal air table. The mass of the spring is negligible. You move the block to the right along the surface by pulling with a constant 20.0 N horizontal force.

what's the block's speed when the black of the block reaches point B, which is 0.25 m to the right of point A.

A 60.0 kg trunk starts at rest on a student's dorm room floor. The student pushes the trunk a distance of 10.0 m along a straight line. The student accomplishes this by exerting on the trunk a constant force of 300 N, directed 20 degrees below the horizontal. The coefficient of kinetic friction between the trunk and the floor is 0.250 . In the following, consider the period of time during which the student pushes the trunk along the 10.0 m distance. For simplicity, assume that g = 9.80 m/ 20° 300 N
