Question

A driver decreases the speed of a car from 25m/s to 10m/s in 5sec find the acceleration of the car

Answer 1

Answer:

-3 m/s²

Explanation:

given:

initial velocity: 25 m/s

final velocity: 10 m/s

time taken: 5 sec

as per question:

acceleration:

$acceleration = \frac{final \: velocity \: - \: initial \: velocity}{time \: taken}$

$\frac{10 - 25}{5} = \frac{15}{5 } = - 3$

therefore, acceleration is -3 m/s² or retardation is 3 m/s²
