Question

The traffic light turns green and the driver of a high-performance car slams the accelerator to the floor. The accelerator registers 22 m/s2. Convert this reading to km/hr2

Answer 1

The conversation will be the following:

$$a = 22\dfrac{m}{s^2} =22\cdot \dfrac{ 10^{-3}km}{(1/3600)^2hr^2} = 22\cdot12960\dfrac{km}{hr^2} = 285120\dfrac{km}{hr^2}$$

Answer. a = 285120 km/hr^2
