E3. A block of mass 1.00 kg sits on an inclined plane as shown. (Figure 1)A force of magnitude 50.0 N is pulling the block up the incline. The coefficient of kinetic friction between the plane and the block is 0.500. The inclined plane makes an angle 10.0 degrees with the horizontal.

What is the total work Wfric done on the block by the force of friction as the block moves a distance 6.00 mm down the incline?

E12. On a frictionless horizontal air table, puck A (with mass 0.254 kg ) is moving toward puck B (with mass 0.366 kg), which is initially at rest. After the collision, puck A has velocity 0.119 m/s to the left, and puck B has velocity 0.654 m/s to the right.

a. What was the speed vi of puck A before the collision?

b. Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.

Express all your answer numerically, in Joules.

A spring is attached to an inclined plane as shown in the figure. A block of mass m = 2.75 kg is placed on the incline at a distance d = 0.294 m along the incline from the end of the spring. The block is given a quick shove and moves down the incline with an initial speed v = 0.750 m/s. The incline angle is θ = 20.0°, the spring constant is k = 450 N/m, and we can...

A block of mass m = 3.5 kg is on an inclined plane with a coefficient of friction μ1 = 0.23, at an initial height h = 0.46 m above the ground. The plane is inclined at an angle θ = 42°. The block is then compressed against a spring a distance Δx = 0.11 m from its equilibrium point (the spring has a spring constant of k1 = 39 N/m) and released. At the bottom of the inclined plane...

A block of mass m1 = 6 kg on a rough 30°-inclined plane is connected to a 4-kg mass (m2) by a string of negligible mass passing over a pulley shaped like a ring. The 2-kg pulley has radius 20 cm and rotates about its symmetry axis of rotation. The string causes the blocks and the pulley to rotate without slipping and without friction. The 6-kg block (m1) on the 30°slope is initially pressed against a spring near the bottom...

A block of mass m2 = 15 kg on a rough 30°-inclined plane is connected to a 5-kg mass (m1) by a string of negligible mass passing over a pulley that is shaped like a disk. The 2-kg pulley has radius 15 cm and rotates about its symmetry axis of rotation. The string does not slip on the pulley and causes the pulley to rotate about a fixed horizontal axle through its center of mass. When this system is released...
