Two masses m1 and m2 are connected by an ideal spring and placedon a horizontal frictionless surface as shown. they are pulledapart so that the spring is stretched an amount x0 and then theyare released simultaneously. the constant for the spring is kN/m.
Find the period of the motion.Find the maximum velocity of each block relative to the surface.
A block of mass 2.0 kg is pushed against a vertical wall by a horizontal push (P) of 50.0 N. The block does NOT move. Assuming that the coefficient of the static friction, k, is equal to 0.60. Find the force AND the direction of the friction.
