Determine the instantaneous speed of the body, the motion of which is described by the equation S = 0.5 t (m)

Given: the equation of motion of the body S = 0.5t.

Since the function along which the coordinate of the body changes is linear (the exponent is 1), the speed of this body will be constant and it can be defined as a first-order derivative of a given function:

V = S ‘= (0.5t)’ = 1 * 0.5 = 0.5 m / s.

Answer: The instantaneous speed of the body is 0.5 m / s.
