i don't know how to start the problem.

An object moving with constant acceleration has ve- locity v = 55.8 m/s when it is at x = 5.5 m and v = 100.4 m/s when it is at x = 10.5 m. What is its acceleration? How much time does it take for the particle to accel- erate from 55.8 m/s to 100.4 m/s? How fast will the particle be...

The brakes on your automobile are capable of creating acceleration of 14 ft/s2. If you are going 82 mi/hr and sud- denly see a state trooper, what is the minimum time required to get your car to 55 mi/hr? How far do you travel while returning to the legal speed limit?

Assuming that the human body can survive a maxi- mum continuous acceleration of 6.40 m/s2, calculate the mini- mum time in which a spaceship can accelerate from 0 m/s to 3.0× 107 m/s, that is, to a velocity that is 10% the velocity of light.

You are driving along the New York State Thruway in a line of cars all traveling at a constant speed of 106.8 km/hr. The car in front of you applies its brakes for maximum accelera- tion. You then apply your brakes to achieve the same maximum acceleration after only a 1 s delay due to...
