The 2 kg mass collar moves freely along the smooth vertical rod. The collar is pulled by a spring of stiffness k = 200 N/m k= 200 N/m 0.6 m ww and a cable. The collar is released from rest at position 1 with the spring stretched 0.075 m. Determine the 0.6 m velocity of the collar at position 2 if a constant force P = 100 N is A 30º %3D

The roller coaster car has a mass of 900 kg, including its passenger. It is released from rest at the top of the hill A. Neglect friction, the mass of the wheels, and the size of the car.

A 5-kg collar can slide on a frictionless horizontal rod and is attached to a spring of constant k= 125 N/m. It is acted upon by a periodic force of magnitude F = F, cos wt, where Fo= 10 N and w = 5 rad/s. Determine the displacement and velocity of the collar at t = 0.2 s assuming that the initial conditions are zero. F = F, cos wt
