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.

Activity 1. An automobile has a speed of 90 km/hr when the brakes are applied. The car is slowed down at the rate of 4 m/s2. What time is required to stop the car, and how far will it travel before stopping?
A group of friends regularly enjoys white-water rafting and they bring piston water guns to shoot water from one raft to another. One summer they notice that when on a placid part of the river without current they are drifting apart after a few volleys at each other. They wonder if the jet being ejected out of the piston gun has enough momentum to force the shooter and raft backward. Calculate the momentum flux in units of newtons generated by the ejected water with a flow rate of 3 gal/s from a cross sectional diameter of 1.7 in.
