A 125 kg block of wood falls off of the back of a truck that is traveling at 26.5 m/s. It lands flat on the road and skids to a stop in 122 m. Assuming acceleration is constant, what is coefficient of kinetic friction?

Which best describes how fluids change as they travel through different portions of the convection currents? they change to solids at the outer portion of the convection currents. they change to solids at the inner portion of the convection currents. they become more dense at the outer portion of the convection currents. they become more dense at the inner portion of the convection currents

A17,250 kg rocket is pushed with a thrust of 6,450,284 n. what is the acceleration of the rocket?

An ideal otto cycle has a compression ratio of 10.5, takes in air at 90 kpa and 40°c, and is repeated 2500 times per minute. using constant specific heats at room temperature, determine the thermal efficiency of this cycle and the rate of heat input if the cycle is to produce 90 kw of power.
