For shooting practice a person uses a pellet gun and an empty pop can. The pop can rests on a flat surface that has a coefficient of kinetic friction 0.400. The pellet has a mass of 0.170 kg and the pop can has a mass of 0.510 kg. After the pellet is fired and now inside the pop can they slide together for 8.10 m. What was the speed of the pellet?

two blocks are positioned on surfaces, each inclined at the same angle of 49.4 degrees with respect to the horizontal. The blocks are connected by a rope which rests on a frictionless pulley at the top of the inclines as shown, so the blocks can slide together. The mass of the black block is 4.61 kg, and the coefficient of kinetic friction for both blocks and inclines is 0.470. Assume static friction has been overcome and that everything can slide....
Two blocks are connected by a string that goes over an ideal pulley as shown in the figure
Problem# 9: Two blocks are connected by a string that goes over an ideal pulley as shown in the figure. Block A has a mass of 3.00 kg and can slide over a rough plane inclined 30.0° to the horizontal. The coefficient of kinetic friction between block A and the plane is 0.400. Block B has a mass of 2.77 kg. (a)Draw the free body diagram (b)What is the reaction of the surface on block A? (c)What is the friction force? (d)What is the acceleration...

A rail gun uses electromagnetic forces to accelerate a projectile to very high velocities. The basic mechanism of acceleration is relatively simple and can be illustrated in the following example. A metal rod of mass 50.0 gg and electrical resistance 0.300 ΩΩ rests on parallel horizontal rails that have negligible electric resistance. The rails are a distance LLL = 10.0 cmcm apart. (Figure 1)The rails are also connected to a voltage source providing a voltage of VVV = 5.00 VV...

A box rests on top of a flat bed truck. The box has a mass of m = 20 kg. The coefficient of static friction between the box and truck is mu_s = 0.86 and the coefficient of kinetic friction between the box and truck mu_s = 0.67. The truck accelerates from rest to v_f = 19 m/s in t = 12 s (which is slow enough that the box will not slide). What is the acceleration of the box?...
