Blocks of mass m1 and m2 are connected by a massless string that passes over a frictionless pulley. Mass m1 slides on a frictionless surface. Mass m2 is released while the blocks are at rest. The pulley is a solid disk with a mass mp and a radius R. Use conservation of energy ...

Physics
Block A and block B (see figure below) are forced together, compressing a spring (with spring constant k = 2220 N/m) between them 2 cm from its equilibrium length. The spring, which has negligible mass, is not fastened to either block and drops to the surface after it has ...

Physics. PLEASE HELP!
two blocks of masses m1 and m2 (m1>m2) are placed on a frictionless table in contact with each other. A horizontal force of magnitude F is applied to the block of mass m1. if P is the magnitude of the contact force between the blocks, what are the net forces acting on m1 ...

Physics
A m1 = 4.20-kg block on a smooth tabletop is attached by a string to a hanging block of mass m2 = 2.70 kg, as shown in the figure. The blocks are released from rest and allowed to move freely. a) Find the acceleration of the blocks. ___m/s^2 b) Find the tension in the string. ...

PHYSICS
An object is originally moving at 13 m/s at the top of a frictionless, quarter-circular ramp with a radius of R = 13 meters. It then travels on a frictionless horizontal surface, around a frictionless loop of radius r = 2 meters, across another horizontal, frictionless surface...
