Acar travelling at 32 m/s decelerates at a rate of 6 m/s ^ 2 over 4 secondswhat is the final velocity the car

v=8m/s

Explanation

The initial velocity, u, of the car=32m/s

Since the car has decelerated, we negate the acceleration

This implies that,

Time,t=4s

Let v be the final velocity,

using the relation,

We obtain the below by substitution

By cross multiplying we obtain,

v=8m/s

d. air pressure decreases as altitude increases.
