Question

Sahil is going to office in his car. he decreases the speed of car from 25 metre per second to 10 metre per second in 5 seconds .find the acceleration off sahil 's car. ​

Answer 1

Answer:

Acceleration = -3$\frac{m}{s^{2} }$

Explanation:

Given: u = 25m/s^2,                v = 10m/s^2,           time = 5sec

Acceleration = $\frac{v - u}{t}$

         =>  $\frac{10 - 25}{5}$               => $\frac{-15}{5}$            => -3m/s^2
