Answer

$a\approx3.09m/s^{2}$

Work Step by Step

We first convert the velocity into meters per second: $60km/h\times\frac{1000m}{1km}\times\frac{1h}{3600s}\approx16.7m/s$ We know the following equation: $a=\frac{\Delta v}{t}$ We plug in the known values to obtain: $=\frac{16.7m/s}{5.4s}\approx3.09m/s^{2}$
