A ball is kicked at an angle of 30 degrees to the horizon, with a horizontal speed of 33.9 m/s and a vertical speed of 19.6 m/s.
Vy = 19.6 m/s
30°
Vx= 33.9 m/s
Which answer best gives the horizontal distance the ball travels before
returning to its starting height?

What is the conversion factor between kg/m^3 and g/m^3. express your experimental values for the densities in kg/m^3.

How would doubling the made of an object change the objects potential energy

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.)
