Description: a block of ice of mass m 250 kg initially at a temperature of ti 400 c is placed at the top of a ramp of height h 980 m a very large ramp as in the picture the block is released from rest an 56543

Step 1: Calculate the gravitational potential energy of the block of ice at the top of the ramp.

Question

A block of ice of mass 𝑚 = 2.50 kg, initially at a temperature of 𝑇𝑖 = -4.00 °C, is placed at the top of a ramp of height ℎ = 98.0 m (a very large ramp), as in the picture. The block is released from rest, and when it reaches the bottom of the ramp it is traveling at a speed of 5.00 m/s. As the block slides down, there is friction between the ice and the ramp. Solve for the final temperature of the block of ice when it reaches the bottom of the ramp. Ignore heat transfer into the air and ramp (i.e. assume all the internal energy increase occurs in the ice). The ramp angle is 45 degrees. 𝑐𝑖𝑐𝑒 = 2090 J/kg⋅℃, 𝑐𝑤𝑎𝑡𝑒𝑟 = 4186 J/kg⋅℃, 𝐿𝑓,𝑤𝑎𝑡𝑒𝑟 = 333,500 J/kg.
