Question

A car travels with a speed of 30m/s increases its speed to

10m/s in 3 sec. Find the acceleration​

Answer 1

Answer:-

• Initial velocity=30m/s=u
• Final velocity=40m/s=v
• Time=3s

We know that

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

$\\ \sf\longmapsto Acceleration=\dfrac{40-30}{3}$

$\\ \sf\longmapsto Acceleration=\dfrac{10}{2}$

$\\ \sf\longmapsto Acceleration=5m/s^2$
