The acceleration is 4.2 m/s2.

Explanation:

Acceleration is the change in velocity over a periodic of time.

a=vfviΔt, where a is acceleration, vf is final velocity, vi is initial velocity, and Δt is time interval.

Known
vf=35m/s
vi=8.8m/s
Δt=6.3s

Unknown
a

Equation

a=vfviΔt

Solution

a=35m/s8.8m/s6.3s=

a=26.2m/s6.3s=4.2 m/s/s=4.2 m/s2
