Answer on Question #61888-Physics-Other

The traffic light turns green, and the driver of a high-performance car slams the accelerator to the floor. The accelerometer registers 22.0m/s2. Convert this reading to km/min2

Solution

$$a = 22.0 \frac{\mathrm{m}}{\mathrm{s}^{2}} = 22.0 \frac{\mathrm{m}}{\mathrm{s}^{2}} \frac{\mathrm{km}}{1000 \mathrm{~m}} \left(\frac{60 \mathrm{~s}}{\mathrm{min}}\right)^{2} = 22.0 \frac{60^{2}}{1000} \frac{\mathrm{km}}{\mathrm{min}^{2}} = 79.2 \frac{\mathrm{km}}{\mathrm{min}^{2}}.$$

Answer: 79.2 $\frac{\mathrm{km}}{\mathrm{min}^{2}}$.
