Question

a car moving uniformly is brought to stop within a distance 5m in 5 seconds find the acceleration produced​

Answer 1

• Distance=5m
• Time=5s

$\boxed{\sf Speed=\dfrac{Distance}{Time}}$

$\\ \sf\longmapsto Speed=\dfrac{5}{5}$

$\\ \sf\longmapsto Speed=1m/s$

• Initial velocity=u=1m/s
• Final velocity=v=0m/s
• Time=t=5s

We know

$\boxed{\sf Acceleration=\dfrac{v-u}{t}}$

$\\ \sf\longmapsto Acceleration=\dfrac{0-1}{5}$

$\\ \sf\longmapsto Acceleration=\dfrac{-1}{5}$

$\\ \sf\longmapsto Acceleration =-0.2m/s^2$
