Question

A vehicle moving with a uniform acceleration of 2 m/s2 has

a velocity of 4 m/s at a certain time. What will its velocity be
a 1s later,
b 5s later?​

Answer 1

a) 6 m/s

b) 14 m/s

Step-by-step explanation:

Acceleration is change in velocity over change in time.

a) a = Δv / Δt

2 m/s² = (v − 4 m/s) / 1 s

v = 6 m/s

b) a = Δv / Δt

2 m/s² = (v − 4 m/s) / 5 s

v = 14 m/s
