The force shown in the attached figure is the net eastward force acting on a ball. The force starts rising at t = 0.020 s, falls back to zero at t = 0.062 s, and reaches a maximum force of 55 N at the peak. Determine with an error no bigger than 25% (high or low) the magnitude of the impulse (in N-s) delivered to the ball. Hint: Do not use J = F?t. Look at the figure. Find the area of a nearly equally sized triangle.
