Change in velocity in a given period of time?
acceleration
If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.
How do you find acceleration when given time and change of distance and velocity?
vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
How do you find force given mass and change in velocity Equations please?
There is not enough information. Force = Mass*Acceleration. Acceleration is the rate of change in velocity. This requires information on change in velocity as well as the time over which the change took place. There is no information at all on the latter.
How do you find acceleration using velocity and time?
Acceleration = (change in velocity) divided by (time for the change)
