PART B: Directions: Analyze and solve the following momentum and impulse-related problems given below. Use the GRESA method in showing your solution and express your final answer in proper significant figures. 1. If a 30.0-kg boy is riding a 7.0-kg bicycle and has a total momentum of 1 15 kg m/s, what is the velocity of the boy and the bicycle put together? Given & Required: Solution: FA: Equation: 2. Carol who weighs 60.0 kg, is driving her car at a speed of 25.0 m/s. She sees a dog crossing the road and so she steps on the brake to avoid hitting it. Her seatbelt brings her body to a stop in 0.40 s. a) What average force does the seatbelt exert on her? b) If she is not strapped to her seatbelt, and the windshield stops her head in 0.001s, what average force would the windshield exert on her? Given & Required: Solution: FA: Equation
