A car is moving with a velocity 20 "m s"...

A car is moving with a velocity `20 "m s"^(-1)`. The brakes are applied to retard it at a rate of `2 "m s"^2`. What will be the velocity after 5 s of applying the brakes?

To solve the problem, we will follow these steps: ### Step 1: Identify the given information - Initial velocity (u) = 20 m/s - Retardation (a) = -2 m/s² (negative because it is a deceleration) - Time (t) = 5 s ### Step 2: Write down the formula to find the final velocity ...
