Extra Practice1. Batman finally decides that enough is enough

and Deadpool can no longer be allowed to run wild in the city. So he grabs his Batmobile to bring him to justice. How long does it take the Batmobile to accelerate from 70 km/h to 180 km/h over a distance of 180 m?

2. Deadpool, not wanting to caught by Batman, steals the nearest airplane to get away. If the airplane must reach a velocity of 135m/s to take off and can accelerate at 12.7 m/s2, what does the length of the runway need to be in order for Deadpool to take off safely? (not that he is worried about that sort of thing)

3. With what velocity can a car go around a 50m curve if the coefficient if friction is 0.55? [16m/s]

4. What speed is a child being spun if they make 4 loops at a radius of 1.6m in 2.4s? [17m/s]

5. Two children on a spinning ride, Wun at 1.5m and Too at 3.0m. Which is moving faster? Which is accelerating more? [Too and Too]

6. Find the tensions if the sign has a mass of 30kg and the angle is 40 degrees.

7. If a 75kg student in an elevator goes from 1.0m/s down to 5.0m/s down over 5.0m, find their apparent weight.

8. A 75.0kg student is launched up from the bottom of a bungee cord ride at an acceleration of 17.2m/s2. What is their apparent weight (how much do they feel they weigh)?

9. A diver leaps straight up off a 8.5m high diving board at 5.4m/s. Find her final velocity when she hits the water.

10. A frustrated Physics student throws a slinky straight down over the edge of a 62.3m high cliff with a velocity of 12.5m/s. What was the final velocity of the slinky just before hitting the ground?

1. In a James Bond chase, a car drives horizontally off a 720m tall cliff at 125km/h. Find the distance the car lands from the base of the cliff.

11. How tall was a cliff that a biker sped horizontally off at 68km/h if she lands 36m away from the base of the cliff.

12. What force is exerted on a 82kg diver who steps off a 50m high board, and belly flops to a depth of 12cm?
