Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations?

isla had negative acceleration, and hazel had positive.

isla had a different time than hazel.

isla had positive acceleration, and hazel had negative.

isla went a farther distance than hazel.

A47.2 g block of copper whose temperature is 480 k is placed in an insulating box with a 91.8 g block of lead whose temperature is 200 k. (a) what is the equilibrium temperature of the two-block system? (b) what is the change in the internal energy of the two-block system between the initial state and the equilibrium state? (c) what is the change in the entropy of the two-block system? the heat capacities of copper and lead are 386 j/kg·k and 128 j/kg·k, respectively.
