Q1. A toolbox is carried from the base of the ladder at point A. The toolbox comes to a rest on a scaffold 5.0 m above the ground. What is the magnitude of the displacement of the toolbox in its movement from point A to point B?
Q2. A block of ice at 0 degrees C, whose mass is initially 30.0 kg, slides along a horizontal surface, starting at a speed of 5.56 m/s and finally coming to rest after travelling 21.8 m. figure out the mass of ice melted (in grams) as a result of friction between the ice and the horizontal surface.
