Question

consider three quantities time velocity and acceleration the product of the units of to this quantities gives the unit of the third which is the third quantity?

Answer 1

v=u+at(v = final velocity, u = starting velocity, t = time, a = acceleration)
a = v-u/t
acceleration = change in velocity/time
acceleration*time = change in velocity
also we can say
acceleration unit = metre/second square, velocity unit = metre/second, time unit = second
So
m/s^2 * s (acceleration*time) = m/s (velocity)
