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 only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.
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
