Question

A motorcycle took only 6.0 seconds to go from rest to 78 m/s (2.8 x 102 km/hr), earning the
world record for motorcycle acceleration. Calculate the magnitude of the record average
acceleration in m/s2.

Answer 1

The magnitude of acceleration

$$a=\frac{\Delta v}{\Delta t}=\frac{78\:\rm m/s}{6.0\:\rm s}=13\:\rm m/s^2$$
