A 2 kg block and a 3 kg block are pushed across a 2 m long frictionless table. Each block is pushed with a force of 1.75 N. Both blocks start from rest.
a. Compare the work done on the 2 kg block and the 3 kg block. Use calculations or proportional reasoning.
b. Compare the kinetic energies of the two blocks when they reach the end of the table. Use the work-energy theorem to explain your answer.
c. Compare the speed of the 2 kg block to the speed of the 3 kg block at the end of the table.
d. Which block reaches the end of the table first? How do you know?
