1) What is the mass of a boat if it travels at a velocity of 57.0 km/h [E] and has a momentum of 2.15 x 10⁶ kgm/s

2)Use the concept of Newton's second law to explain why a motorcycle can accelerate at a greater rate than a large truck.

3). In video games, high-speed crashes are common. Consider a motorcycle and a car racing against each other down a mountain road. Eventually each vehicle strikes a metal barrier.

1. Compare the masses and speeds of each vehicle. Remember to consider the size of the motor of each vehicle.
2. Define momentum and compare the momentum values for each vehicle.
3. Define impulse. Explain how hitting the barrier changes the momentum of each vehicle.
4. Use the concept of Newton's first law to explain what happens to each driver when they strike the barrier, if they are not wearing a seat belt.
