Question1

The Westin Stamford Hotel in Detroit is 228 m tall. Assume a piece of ice, that initially has a temperature of 0.0°C, falls from hotel roof and crashes to the ground. Assuming that 50.0 percent of the ice’s mechanical energy during the fall and collision is absorbed by the ice and that 3.33 × 105 J is necessary to melt 1.00 kg of ice, compute the fraction of the ice’s mass that would melt.

Question2

The velocity, in the x direction, is given by formula-
v sub x = 5 m/s^2 t + 2 m/s

The area under velocity curve between two times is equal to the displacement (change in position) throughout that time interval.
What is displacement between t = 0 s and t = 10 s? Change of x =?
