A block of weight = 25.0 N sits on a frictionless inclined plane, which makes an angle = 34.0 with respect to the horizontal, as shown in the figure. A force of magnitude F= 14.0 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant ...

A 0.145 kg block is released from rest from the top of a 51.7◦ frictionless incline. When it has fallen a vertical distance of 1.3 m, a 0.00794 kg bullet is fired into the block along a path parallel to the slope of the incline, and momentarily brings the block to rest, ...

A box weighing 136. N rests on a table. A rope tied to the box runs vertically upward over a massless frictionless pulley and a weight is hung from the other end. What is the force that the table exerts on the box if the weight hanging the other side of the pulley weighs: 2....

A block of mass 0.22 kg can slide on a frictionless incline ( = 30) and is connected via a string to a vertical spring (k = 3.6 N/m). The system starts at rest with the spring at its natural length. (a) What is the maximum distance along the incline through which the block ...

A block (mass = 2.9 kg) is hanging from a massless cord that is wrapped around a pulley (moment of inertia = 1.2 x 10-3 kgm2), as the figure shows. Initially the pulley is prevented from rotating and the block is stationary. Then, the pulley is allowed to rotate as the block...

physics
Consider two masses m1 and m2, connected by a spring of spring constant k and an uncompressed length L. The masses are on a frictionless surface. Initially, m2 compresses the spring to L/2 length. At t=0 the system is released. Find the position of the center of mass of the ...
