A rocket powered car is set inside a circular track ingnited. pressure sensors on wall of track measure the centripetal acceleration of the car as function of to be c()=1m/s^6)^+(14m/s^4)^2+(49m/s^2) if radius of the track is 3.78m, what is the tangential acceleration of the rocket car at=4.51s??

What’s #16 asking and how do i solve it?

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.

When the displacement of a mass on a spring is 12a the half of the amplitude, what fraction of the mechanical energy is kinetic energy? at what displacement, as a fraction of a, is the mechanical energy half kinetic and half potential?
