A block of ice at 0oC whose mass initially is m = 42.1 kg slides along a horizontal surface, starting at a speed v0 = 2.35 m/s and finally coming to rest after traveling a distance d = 2.93 m. Compute the mass of ice melted as a result of the friction between the block and the surface. (Assume that all the heat generated owing to friction goes into the block of ice.)

A block of mass m1 = 1.4 kg initially moving to the right with a speed of 3.0 m/s on a frictionless, horizontal track collides with a spring attached to a second block of mass m2 = 2.5 kg initially moving to the left with a speed of 1.8 m/s. The spring constant is 565N/m. What if m1 is initially moving at 3.2 m/s while m2 is initially at rest? (a) Find the maximum spring compression in this case. (b)...

Cart A (mass 2.0 kg) and Cart B (mass 3.0 kg) are separated by a compressed spring and attached to each other by a string. Initially they are sitting at rest on a frictionless surface. When the string is burned, Cart A moves to the left at 1.5 m/s. Cart B moves to the right and encounters a rough surface. Cart B comes to a stop after traveling a distance of 0.35 m on the rough surface. What is the...

A block of mass m is initially at rest at the top of an inclined plane, which has a height of 5.6 m and makes an angle of θ = 21° with respect to the horizontal. After being released, it is observed to be traveling at v = 0.55 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the block and the plane is μp = 0.1, and the coefficient...

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...
