(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A bicycles accelerates from rest, covering 16 metres in 4 seconds. The total mass of the bicycle and its rider it 90kg. What is its average acceleration during this time?

2. Relevant equations

x = ut + 0.5at^2

v=xt

a=vt

3. The attempt at a solution

v = x/t

v = (16)/(4)

v = 4 m/s

F = mv/t

F = (90)(4)/4

Fnet = 90N

Fnet = ma

90 = 90a

A= 1 m/s^2<--WRONG!! - How?

A=2ms <--- RIGHT
