Question

distance travelled by a moving car with velocity 15m/s in 2s,decelerate at 2m/s equal to

Answer 1

since it is decelerating take '-' sign

Answer 2

Answer:

The distance covered by the car is 26 meters.

Explanation:

Given that,

Speed of the car, u = 15 m/s

Time, t = 2 s

Acceleration of the car, $a=-2\ m/s^2$

Let s is the distance covered by the car. It is given by :

$s=ut+\dfrac{1}{2}at^2$

$s=15\times 2+\dfrac{1}{2}(-2)\times 2^2$

s = 26 meters

So, the distance covered by the car is 26 meters. Hence, this is the required solution.
