A student mixed 75.0 mL of water containing 0.75 mol HCI at 25* C with 75.0 mL of water containing 0.75 mol of NaOH at 25*C in a foam cup calorimeter. The temperature of the resulting solution increased to 35*C. How much heat in kilojoules was released by...

A truck of mass 7520 kg is traveling along a level road at an initial speed of 32.9 m/s and then slows to a final speed of 17.9 m/s. Find the total work done on the truck.

A mass and spring are arranged on a horizontal, frictionless table as shown in the figure below. The spring constant is k = 480 N/m, and the mass is 4.8 kg. The block is pushed against the spring so that the spring is compressed an amount 0.31 m, and then...
