4. A 6-kg block (my), initially at rest on a rough shelf, is connected to a 4-kg block (m2) that hangs by an inextensible string of negligible mass passing over a pulley. The uniform disk-shaped pulley, having a mass of 3.0-kg and a radius of 10 cm, rotates about the symmetry axis through its center. The 6-kg block, which is attached to the spring, is initially pushed against the spring compressing it a distance of 30 cm from its equilibrium...

A hanging weight, with a mass of m1 = 0.365 kg, is attached by a rope to a block with mass m2 = 0.825 kg as shown in the figure below. The rope goes over a pulley with a mass of M = 0.350 kg. The pulley can be modeled as a hollow cylinder with an inner radius of R1 = 0.0200 m, and an outer radius of R2 = 0.0300 m; the mass of the spokes is negligible. As...

A block of mass m1 = 2.40 kg is connected to a second block of mass m2 = 1.80 kg, as shown in the sketch. When the blocks are released from the rest, they move through a distance d = 0.50 m, at which point m2 hits the floor. Given that the coefficient of kinetic friction between m1 and the horizontal surface is Hk 0.450, find the speed of the blocks just т before lands. т2

A block of mass m1= 4.00 kg moves on the surface of a horizontal
table. The coefficient of kinetic friction k between the table top
and m1 is equal to 0.350. Block 2 of mass m2= 2.00 kg is tied to m1
via a string that passes over a frictionless, massless pulley. The
two blocks start from rest and m2 drops by a distance L =1.75 m to
the floor.
Use the work-energy theorem to determine the speed v of...

Block 1, of mass m1 = 1.10 kg , moves along a frictionless air track with speed v1 = 29.0 m/s . It collides with block 2, of mass m2 = 45.0 kg , which was initially at rest. The blocks stick together after the collision. (Figure 1) Find the magnitude pi of the total initial momentum of the two-block system. Find vf, the magnitude of the final velocity of the two-block system. What is the change ΔK=Kfinal−Kinitial in the...

In the figure below, a 4.0 kg block is accelerated from rest by a compressed spring of spring constant 600 N/m. The block leaves the spring at the spring's relaxed length and then travels over a horizontal floor with a coefficient of kinetic friction uk= 0.30.The frictional force stops the block in the distance of D = 8.0 m. -- No friction a) Find the increase in the thermal energy of the block-floor system b) What is the original compression...
