Question 1: A girl and her 40kg dog are out walking one summer day when they come to a road they need to cross. 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.
