An object accelerates from rest to 85m/s over a distance of 36m. What acceleration did it experience?

Suvat

we have s, u, v and we want a

the suvat equation with these values in is: v^2 = u^2 - 2as

so a = (-v^2 + u^2) / - 2s

plug numbers in

a = (-85^2 + 0^2) / - 2*36 = 7225/72 = 100.3 ... ms^-2
