Question

A 522 g particle moving along the x-axis experiences the force shown in FIGURE. The particle�s velocity is 2.65 m/s at x=0. What is its velocity at x=1.01 m? (F=6.2 N, s=1.01 m)

Answer 1

I didn't get.. what you meant in the bracket (F= 6.2N, s=1.01m) ??

looking at the graph.. all you need to do is find the work done from x=0 to x = 1.01 m.. and then invoke the work energy theorem!
