Question
A 3.50 kg block of ice slides down a ramp. The block starts at the top of the ramp from rest, and when it reaches the bottom of the ramp it is traveling at a speed of 2.00 m/s. The ramp is 4.50 m high vertically. Assume that the block of ice and ramp form a closed system (no surrounding air), and that any change in internal energy of the system occurs in the block of ice, not in the ramp.
Cm-ice = 2090 J/kg·K g=9.80m/s^2
a) Find the change in the mechanical energy (potential + kinetic) of the block from the top to the bottom.
b) Find the change in the internal energy of the block from the top to the bottom.
c) Find the change in temperature of the block from the top to the bottom
