2 A rocket of mass 3.20 x 10' kg is in flight, but still under the full influence of earth's
gravity. Its thrust is directed at an angle of 54.0° above the horizontal and has a
magnitude of 9.40 x 10' N. Find the magnitude and direction of the rocket's acceleration.
Give the direction as an angle above the horizontal

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

With i really need the correct answer!
