Question

A 5.06kg particle moving along the x-axis experiences the force shown, where Fmax = 7.51N, Fmin = -7.51N, d1 = 3.15m, d2 = 6.30m, dz = 9.45m, and d4 = 12.50m. At x = 0.00m the particle's velocity is 4.32m/s. FN) max 14 x(m) F MID What is its velocity at x=6.30m? Submit Answer Tries 0/10 What is its velocity at x=12.60m? Submit Answer Tries 0/10
