Conservation of energy: Spring block on an incline. - An object of mass m starts from rest and slides a distance d down a frictionless incline of angle . While sliding, it contacts an unstressed spring of negligible mass as shown in Figure. The object slides an additional distance x as it is brought momentarily to rest by compression of the spring (of force constant k). Find the initial separatio...

Newton's word prob - m2= 3.00kg, m1 = 5.00kg. h=4 Two objects are connected by a light string passing over a light frictionless pulley . The object of 5.00kg mass is released from rest. Using the principle of conservation of energy. (a) determine the speed of 3.00kg object just as the 5.00kg object hits the ground. (b) find the maximum height to which the 3kg object rises. (c) How will this ...

Newton's Law (5.120) - (See attached file for full problem description with diagram) Moving Wedge. A wedge with mass rests on a frictionless horizontal table top. A block with mass is placed on the wedge (the figure a). There is no friction between the block and the wedge. The system is released from rest. 1. Calculate the acceleration of the wedge. 2. Calculate the horizontal comp...

A block is released from rest at the top of a curved-shaped frictionless wedge which rests on a frictionless horizontal surface. Its velocity at the time of leaving the wedge is known. To determine the velocity of the wedge after the block reaches the horizontal surface and the height of the wedge. - 10. A small block of mass m1 = 0.480 kg is released from rest at the top of a curved-shaped frict...

Mechanics: Conservation of momentum, friction, kinetic energy and motion. - A 62.0 kg person running at an initial speed of v1 = 3.90 m/s jumps onto a m = 124 kg cart initially at rest. (Figure) The person slides on the cart's top surface and finally comes to rest relative to the cart. The coefficient of kinetic friction between the person and the cart is 0.350. Friction between the cart and groun...
