Question

a bike accelerates uniformly from rest to a speed of 7.10m/s over a distance of 35.4m.Determine the acceleration of the bike.

Answer 1

\[v ^{2}=u ^{2}+2as\]
\[7.1^{2}=2\times a \times 35.4\]
\[a = 0.7120 m/s ^{2}\]

Answer 2

is the u^2 is already given as a value of 2?

Answer 3

no u is initial speed - which is 0 - as it starts from the rest
