The forces shown in the force vs. time diagram in the figure below act on a 1.8 kg particle. The vertical divisions on the graph represent 4.5 N and the horizontal divisions represent 0.50 s.(a) Find the impulse for the interval t = 0 to t = 1.5 s.Enter a number.1Your answer is incorrect.Your response differs from the correct answer by 10% to 100%. N·s(b) Find the impulse for the interval t = 0 to t = 2.5 s.Enter a number.2 N·s(c) If the forces act on a 1.8 kg particle that is initially at rest, find the particle’s speed at the following times.1.5 s
