Question

Calculate the acceleration of a car if it's velocity increases from 15 m/s to 75m/s in 5 seconds. ​

Answer 1

• initial velocity=u=15m/s
• Final velocity=v=75m/s
• Time=t=5s

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

$\\ \sf\longmapsto Acceleration=\dfrac{75-15}{5}$

$\\ \sf\longmapsto Acceleration=\dfrac{60}{5}$

$\\ \sf\longmapsto Acceleration=12m/s^2$
