PHYSICS Problem Solving: 1. In 2019, Sammy Miller drove a rocket powered dragster from rest to 402m (1/4 mile) in a record 3.22s. What acceleration did he experience? 2. If a car is going 100. km/hr as it passes a bystander, then passes another bystander 20.0 seconds later when it's going 120. km/hr, what is the car's average acceleration? Show all work as demonstrated in the lessons. 3. A submarine is travelling at a constant velocity of 20.0 m/s for 2.00 hours. What distance did it travel? Show all work as demonstrated in the lessons. 4. A stationary boat accelerates to 90. km/hr over 1.0 km. What is the time it takes to do this? Show all work as demonstrated in the lessons. 5. A braking train can decelerate at 0.400 m/s2. If the train is travelling at 160. km/hr and needs to plan to stop at a pick-up area. How far in advance does it need to apply the brakes? Show all work as demonstrated in the lessons
