1. A plane accelerated from a speed of 2.0 m/s at the rate of 3.0 m/s2 over a distance of 530 m. What is its speed after traveling this distance?
2. A jet plane must achieve a velocity of 71 m/s for takeoff. From rest and with a 1,000 m long runway, what must the acceleration be?
3. The highest deceleration survived by a human (voluntary) is 452.76 m/s2. In 1954, Colonel John Stapp rode a rocketpowered sled that had a top speed of 632 mph. Colonel Stapp came to stop in how many meters?
4. A car decelerates at 8.0 m/s2 from 30 m/s to zero. How far does the car travel?
5. Scientists are developing new types of guns that might someday be used to launch satellites as if they were bullets. One such gun can give a small object a velocity of 3500 m/s moving through a distance of only 0.02 m. What acceleration does this gun give the object?
6. Highway safety engineers build soft barriers so that cars hitting them will slow down at a safe rate. A person wearing a shoulder harness can survive a car crash if the acceleration is smaller than 300 m/s2. Assuming constant acceleration, how thick should barriers be to stop car going 65 mph?
7. A baseball pitcher can throw a fastball at 44 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves the ball from rest through a distance of 3.5 m. Calculate the acceleration of the ball.
8. At an accident scene, 276m long skids marks are found on the road. If the car that made these skid marks can decelerate at –9.8 m/s2, how fast was the car going before braking?
9. Time travel requires vehicles that can move at close to the speed of light, 3x108 m/s. Starting from rest, how far would such a vehicle have to travel if the acceleration is 20 m/s2?

Nobody will do your work for you, Ray.
But I will be glad to look over your answers.
