A motorcycle is speeding along at a velocity of120kph. Then, it changes to a velocity of 150 kph for 2 minutes. What is the motorcycle's averange acceleration?

a=v-u/t

a=acceleration

v=final velocity

u=initial velocity

t=tme taken

we need to convert from kph to ms⁻¹

v = 150*1000/60*60 = 41.67ms⁻¹

u = 120*1000/60*60 = 33.33ms⁻¹

t = 2*60 = 120s

a=41.67-33.33/120

a=8.34/120

a=0.0694ms⁻²
