Question

A car starting from 5m/s acquires a velocity of 16m/s in 3s .Calculate the acceleration.​

Answer 1

Answer:

here initial velocity =5m/s

final velocity = 16 m/s

Time taken = 3sec

Acceleration =Change in velocity / time taken

= (16 -5)/3

= 11/3

=3.667 m/s^2

Answer 2

• initial velocity=u=5m/s
• Final velocity=v=16m/s
• Time=t=3s

We know

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

$\\ \rm\longmapsto Acceleration=\dfrac{16-5}{3}$

$\\ \rm\longmapsto Acceleration=\dfrac{11}{3}$

$\\ \rm\longmapsto Acceleration=3.6m/s^2$
