Q6) (10 points) A 4.0-kg block slides along a frictionless surface with a constant speed of 5.0 m/s as shown. Two seconds after it begins sliding, a horizontal, time-dependent force is applied to the mass. The force is removed eight seconds later. The graph shows how the force on the block varies with time. 4.0 kg Force (N) 10 сл 0 2 Calculate the speed of the block at t = 8 seconds? 4 6 8 10 Time (s)
