15 J of work were expended moving an 18 kg block. At what velocity did the block move?

A
1.3 m/s

Explaination

To solve for velocity, you should use the formula W = KE, where Work = W, and Kinetic Energy = KE. This is because any work that is done to accelerate an object is converted to the kinetic energy of that object (the work-energy theorem). So, $2173_w87_h37.png$. Plugging in the block's weight (18 kg) and the work done (15 J) will give you a velocity of 1.3 m/s.
B 1.1 m/s

C 0.9 m/s

D 0.7 m/s
