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...
