1) A larger chicken starts at rest and begins to run along the ground with a constant acceleration. If the chikcen travels a distance of 6.2 meters from its starting point in the first 11.0 seconds, calculate the acceleration of the chicken. Show all of your work, including a diagram that indicates the directions of all vectors in the problem.
2) a car traveling at initial velocity 22 meters per second slows down and stops in a distance of 80 meters.
a) Draw a diagram of the situation, showing the direction of all vectors in the problem.
b) Find the acceleration of the car while stopping.
c) Find the speed the car had at the 40 meter point of the trip.
3. Sound in air travels at a speed of about 343 meters per second. Calculate the time it takes sound to travel 1000 feet.
4) A car traveling at an unknown initial speed accelerate (speed up) at 2.0 m/s^2, and we find that 3 second later the car is 15.5 meters away from its starting point.
a) Draw a diagram of the situation and make a list of the given information.
b) What was the initial velocity of the car?
5) A car traveling at 31 meters per second (about 70 miles per hour) slams on the brakes and decelerates at a rate of 7 m/s^2.
a) Find the distance the car will travel until it stops.
b) If this car slammed on its brakes when it was half a football field length (50 yards) away from a deer in the road, did the car stop before hitting the deer? Show your work.
