The block in the figure below lies on a horizontal frictionless surface and is attached to the free end of the spring, with a spring constant of 65 N/m. Initially, the spring is at its relaxed length and the block is stationary at position x = 0. Then an applied force with a constant magnitude of 2.8 N pulls the block in the positive direction of the x axis, stretching the spring until the block stops.

Assume that the stopping point is reached.

(a) What is the position of the block?

m

(b) What is the work that has been done on the block by the applied force?

J

(c) What is the work that has been done on the block by the spring force?

J

During the block's displacement, find the following values.

(d) The block's position when its kinetic energy is maximum.

m

(e) The value of that maximum kinetic energy.

mJ
