On the left is the problem. On the right is what I came up with. The question is to calculate the work done by "The truck on the crate (Normal force)", "The Earth on the crate (perpendicular to truck bed)", "The Earth on the crate (parallel to truck bed)", and "Friction".

What accounts for an increase in the temperature of a gas that is kept at constant volume? a. energy has been removed as heat from the gas. b. energy has been added as heat to the gas. c. energy has been removed as work done by the gas. d. energy has been added as work done by the gas.

Ahorizontal force of 400.0 n is required to pull a 1760 n truck across the floor at a constant speed. find the coefficient of sliding friction.
