Evaluate the velocity of cart
A cart of mass 2.3 kg is moving with a velocity of 15.2 m/s. It makes a head-on perfectly inelastic collision with a stationary cart B with mass 8.1 kg causing them to travel with a velocity 10.94 m/s. What is the velocity of cart B?

Clothing has a static coefficient of friction against steel in the range 0.60 to 1.0 and a kinetic coefficient in the range 0.40 to 0.70. What is the minimum rotational frequency in rpm, for which the ride is safe?
A very massive object traveling at 100 m/s in the +z direction strikes a very light object that is initially at rest. If the collision is totally elastic, what is the velocity of the heavier object?
The convection coefficient is 5.5 W/m^2 *k and radiation coefficient is 10 W/m^2 * k. Determine the heat rate per unit length from the pipe (W/M) and the insulation outer surface temperature (K).
