In the drawing, the weight of the block on the table is 405. N and that of the hanging block is 191. N. Ignore friction, the mass of the rope, and the mass of the pulley. Find the acceleration of the two block system in m/s2.

With a mass = 10 k .. the horizontal surface on which the block slides is frictionless. The speed of the block before it touches the spring is 6.0 m/s. How fast is he block moving at the instant the spring has been compressed 15 cm? K=2.0kN/m

A 2.6 kg block slides down a 25 inclined plane with constant acceleration. The block starts from rest at the top. At the bottom, its velocity is 0.75 m/s. The incline is 1.6 m long. (a) What is the acceleration of the block? (b) What is the coefficient of friction?

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...

A 0.55 kg block of ice is sliding by you on a very slippery floor at 4 m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with the ice block for 0.0025 seconds. The block eventually slides at an angle of 23 degrees from its original ...

Two blocks move along a linear path on a nearly frictionless air track. One block, of mass 0.107 kg, initially moves to the right at a speed of 4.70 m/s, while the second block, of mass 0.214 kg, is initially to the left of the first block and moving to the right at 6.80 m/s. ...
