1.) Landing with a speed of 79.6 m/s, and traveling due south, a jet comes to rest in 965 m. a.) Assuming the jet shows with constant acceleration, find the magnitude and direction of its acceleration. B.) to the south or to the north?
2.) a firefighter slides down a pole in a fire station with an acceleration of 8.2 m/s2. If the firefighter starts at rest and slides for a distance of 3.7 m , what is his final speed?
3.) a baseball player is dashing toward home plate with a speed of 3.0 m/s when she decides to hit the dirt. She slides for 1.5 s , just reaching the plate as she stops. A. What’s her acceleration? (Assume her running direction is the positive direction.) B. How far does she slide?
4.) when you see a traffic light turn red, you apply the brakes and stop with constant acceleration. If your initial speed was 28 m/s , what’s your average speed during braking?
