You cannot.
You cannot.
If you are only given total distance and total time you cannot. If you are given distance as a function of time, then the first derivative of distance with respect to time, ds/dt, gives the velocity. Evaluate this function at t = 0 for initial velocity. The second derivative, d2s/dt2 gives the acceleration as a function of time.
You cannot. You must have distance (or displacement). If you know it is from a standing start then accelaration will do.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
You can use the equation: distance = (initial velocity + final velocity) / 2 * time. This formula assumes constant acceleration.
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.
You can't. Acceleration is change in velocity. If given a constant velocity, the acceleration is zero.
You can find the distance using the equation: distance = (final velocity)^2 / (2 * acceleration). Square the final velocity, divide it by twice the acceleration to get the distance traveled before coming to a stop.
To get the potential energy when only the mass and velocity time has been given, simply multiply mass and the velocity time given.
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
In that case, you don't have enough information.
you measure it
