Question

fill in the blank question a car is traveling at a velocity of 30 m/s. the car then starts to accelerate at 5 m/s². in the 4 seconds the car is accelerating, it gained \boxed{} m/s.

Explanation:

Step1: Recall velocity gain formula

Velocity gain $\Delta v = a \times t$

Step2: Substitute given values

$a = 5\ \text{m/s}^2$, $t = 4\ \text{s}$, so $\Delta v = 5 \times 4$
