A 0.400kg0.400kg block is initially at rest on a horizontal surface, and is attached to an initially unstreteched spring with a force constant of 2.00N/m2.00N/m. The coefficient of kinetic friction between the block and the surface is 0.4000.400. A constant force of 2.30N2.30N to the right is applied to the block.

(A) Draw a free body diagram showing all forces on the block as it moves to the right.

Determine
(B) the initial Kinetic Energy of the block:  J, and
(C) the initial Potential Energy (i.e. the initial energy stored in the spring):  J

The block moves 0.600 m to the right of its starting position. Determine
(D) the work done by the applied force:  J,
(E) the work done by the force of friction :  J,
(F) the work done by the normal force:  J and,
(G) the work done by the force of gravity:  J.

(H) the final Potential Energy (i.e. the final energy stored in the spring):  J

Using work and energy methods and your results above, determine
(I) the final Kinetic Energy of the box:  J, and
(J) the final speed of the box:  J, and #### Earn Coins
