When an object falls from a height, the distance s (metres), it travels in time t (seconds) is given by the equation s = 4.9t2. Is the distance travelled proportional to time?
The equation of distance travelled is given by s = 4.9t2
The above equation is not of the form y = kx, where k is the constant of proportionality.
Thus, the distance travelled is not proportional to the time taken.
