Question 3: A projectile of mass m = 10 kg traveling with the velocity v = 50 m/s strikes and becomes embedded in a massless board supported by a spring of stiffness k = 6.4 × 101 N/m in parallel with a dashpot with the coefficient of viscous damping c = 400 Ns/m. Determine the time required for the board to reach maximum displacement and the value of the maximum displacement, also plot the response and show them on the graph. x(t) k www V C m
