The pavement is hot, so the girl borrows a skateboard for her dog and gives him a push to get him across the road so that his feet won’t burn. If the road is 10 meters wide, using the EQUATION OF WORK AND ENERGY, find the magnitude of the initial velocity required so that the dog will coast across the road and come to rest at 10 meters away on the other side of the road. The coefficient of kinetic friction between the wheels and the pavement is 0.3.arrow_forward3. An elevator has mass 600 kg, not including passengers.
