Question

A truck accelerates from a stop to 27m/sec in 9 minutes. What was the trucks acceleration?

Answer 1

Vi = 0 m/s
Vf = 27 m/s
t = 9 min = 540 s
1 min = 60 s
9 min = 540 s
a = ? m/s^2.

vf = vi + at
27 = 0 + 540a
27 = 540a
27/540 = 540a/540
27/540 = a
0.05 = a.

The truck's acceleration was 0.05 m/s^2.
