Work Energy Problem 3

A 1.0 kg block moves along the x-axis. It passes x = 0 with a velocity v = 2.0 m/s. It is then subjected to the force shown in the graph below.

a. Which of the following is true: The block gets to x = 5 m
with a speed greater than, less than, or equal to 2.0 m/s.
State explicitly if the block never reaches x = 5 m.

b. Calculate the block's speed at x = 5 m.
