a 3220 kg truck is rolling down a frictionless 8.30° slope that is 22.0 m long. If its initial speed was 4.71 m/s, how fast is it going at the bottom? (Unit = m/s)​

What if? physicists often measure the momentum of subatomic particles moving near the speed of light in units of mev/c, where c is the speed of light, and 1 mev = 1.6 ✕ 10−13 kg · m2/s2. based on this, what are the units of momentum for a high-speed subatomic particle in terms of fundamental si units?

Select for each of the following statements whether it is correct or incorrect. (a) in an isothermal expansion of an ideal gas. (b) the temperature remains constant. (b) the pressure remains constant. (c) there is work done by the gas. (d) there is heat added to the gas. (e) the change in internal energy equals zero.

Using the free-body diagram, calculate the net force acting on the sled. is the sled in a state of dynamic equilibrium?
