Question

A vehicle Moving with a uniform acceleration 2m/s² has a velocity of 4m/s a certain time. What will its velocity be
(a) 1s later
(b) 5s later ​

Answer 1

This motion has an uniform acceleration.

Taking  $V(0)= 4m/s$, we have,

The equation V(t) of motion is: V(t) = $4 + 2 \cdot t \ (V_{0} + a \cdot t)$

Therefore

A)

$V(1) = 4 + 2 \cdot 1 = 6m/s$

B)

V(5) = $4 + 2 \cdot 5 =14m/s$

These are your answer.
