A car traveling in a straight line has a velocity
of 5.25 m/s at some instant. After 4.27 s, its
velocity is 9.38 m/s.
What is its average acceleration in this time
interval?
Answer in units of m/s.

Answer 1

Divide the change in speed by the given time:

a = (9.38 m/s - 5.25 m/s) / (4.27 s) ≈ 0.967 m/s²
