Starting from rest, it takes 1 second for m1 to fall 1.5m. A ring of unknown mass sits on top of m1 as it falls. If m1=2kg and m2=2.5kg, and the incline is frictionless, what force does m1 put on the ring?
Show the complete solution. Put notes on steps. The wooden block (mass m = 0.6165 kg) is released from rest at A by a compressed spring (compressed length 0.6 m, undeformed length 1 m, spring constant k = 150 N/m). The block is allowed to slide through the rough horizontal surface (A to B), then along the smooth circular ramp (B to C, central angle 0 = 45°, until the block is released after point C. Calculate the speed of the block at points B and C. Also, what is the magnitude of the normal force exerted to the block just before the block leaves the ramp? Neglect the geometry of the block.NOTE: Use Work-Energy Method to solve for the speeds; use Force-Mass-Acceleration (FMA) Method to compute for the normal force.
A system of a 50 kg empty trolley and a 140 kg counterweight is shown in Figure below. After the counterweight has dropped 10 m from rest, the velocity of the trolley is 6 m/s. If all frictional resistances can be regarded as a single force F acting on the trolley parallel to the inclined plane, calculate the resistance of the force. Note that pulleys are smooth and frictionless.
As indicated in the illustration, two blocks are connected by an inextensible cable. Block A weighs 178.6 kg, while B weighs 252 kg. If the system is released from rest, calculate the acceleration (in m/s2) of block B. For simplicity, let us suppose that the coefficient of friction between block A and the plane is μk = 0.24 and that the pulley is both weightless and frictionless. Make use of the formula g = 9.81 m/s2.

The carnival ride from Prob. 12.51 is modified so that the 80-kg riders can move up and down the inclined wall as the speed of the ride increases. Assuming that the friction between the wall and the carriage is negligible, determine the position h of the rider if the speed v0 = 13 m/s.Reference to Problem 12.51:
During braking, a truck has a steady deceleration of 7.0 m/s². A box sits on the platform of this truck. The box begins to slide when the braking begins and, after sliding a distance of 2.0 m (relative to the truck), it hits the front of the truck. With what speed (relative to the truck) does the box hit? The coefficient of kinetic friction for the box is μk=0.50.
15 kg boxes are being transported around a curve via a conveyor belt as shown to the right.
