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...

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...

A box of mass 40 kg is initially at rest on a flat floor. The coefficient of kinetic friction between the box and the floor is µk = 0.40. A woman pushes against the box with a force of 250 N that makes an angle of 30° with the horizontal until the box attains a speed of 1.0 m/s. (a) What is the change of kinetic energy of the box? (b) What is the work done by the friction force...

7.7. Please answer all the
questions and show your work.
A 4.20-kg block is set into motion up an inclined plane with an initial speed of v_1 = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of theta = 30.0 degree to the horizontal. For this motion, determine the change in the block's kinetic energy. J For this motion, determine the change in...

A 28.0-kg block is initially at rest on a horizontal surface. A horizontal force of 73.0 N is required to set the block in motion, after which a horizontal force of 55.0 N is required to keep the block moving with constant speed. (a) Find the coefficient of static friction between the block and the surface. (b) Find the coefficient of kinetic friction between the block and the surface.

6 points PSE6 7.P031. 4. My Notes A 38.0 kg box initially at rest is pushed 5.20 m along a rough, horizontal floor with a constant applied horizontal force of 135 N. If the coefficient of friction between box and floor is 0.300, find the following. (a) the work done by the applied force (b) the increase in internal energy in the box-floor system due to friction (c) the work done by the normal force J (d) the work done...

A 6.00 Kg mass initially at rest slides down a ramp which makes
an angle of with horizontal at a
height of 5.0 m above the bottom of the slide and hits a 10.00 Kg
mass which is at rest, after collision, the 6.00 Kg mass bounces
back with a velocity of 0.60 m/s and 10.0 kg mass slides forward on
level. If the coefficient of kinetic friction for the incline is
0.30 and level is...
