A commuter backs her car out of her garage with an acceleration of 1.40 m/s². (a) How long does it take her to reach a speed of 2.00 m/s? (b) If she then brakes to a stop in 0.800 s, what is her acceleration?

During a hard sneeze, your eyes might shut for 0.38 s. If you are driving a car at 94 km/h during such a sneeze, how far does the car move during that time?

(a) What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 10.7 m/s when going down a slope for 4.81 s? (b) How far does the skier travel in this time?

In order to pass a physical education class at a university, a student must run 1.0 mi in 13.3 min. After running for 10 min, she still has 670 yd to go. If her maximum acceleration is 0.15 m/s?, can she make it? (Assume the student runs at a constant speed for the first 10.0 min.) O Yes O No If the answer is no, determine what acceleration she would need to be successful. (If the answer is yes, enter 0.) |m/s²

What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 11.4 m/s when going down a slope for 3.16 s? (b) How far does the skier travel in this time

A jet plane has a takeoff speed of vto = 72 m/s and can move along the runway at an average acceleration of 1.7 m/s2. If the length of the runway is 1.4 km, will the plane be able to use this runway safely? O Yes O No Defend your answer.

A runner of mass 50.1 kg stařts from rest and accelerates with a constant acceleration of 1.1 m/s2 until she reaches a velocity of 6.5 m/s. She then continues running at this constant velocity. How long in seconds does the runner take to travel 104 m? 载

Without turning around, a dog walks along a long straight path for 4.0 m at 3.0 m/s and then for 2.0 s at 6.0 m/s. What was the average speed of the dog?

(a) What is the magnitude of the average acceleration of a skier who, starting from rest, reaches a speed of 8.06 m/s when going down a slope for 1.61 s? (b) How far does the skier travel in this time?

A train is traveling at 50 m/s and needs to come to a stop before it hits an empty car abandoned on the tracks. It can decelerate at a rate of 2 m/s² and only has 300 meters to stop. Will it stop in time?
