Question

A body is moving with 20m/s attained 100m/s in 5 seconds then find its acceleration

Answer 1

Answer:-

• initial velocity=u=20m/s
• Final velocity=v=100m/s
• Time=t=5s

We know

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

$\\ \sf\longmapsto Acceleration=\dfrac{100-20}{5}$

$\\ \sf\longmapsto Acceleration=\dfrac{80}{5}$

$\\ \sf\longmapsto Acceleration=16m/s^2$

Answer 2

Answer:

Acceleration is 16m/s².

Explanation:

v = 100m/s

u = 20m/s

t = 5sec

a = (v-u) /t

Therefore, a = (100-20)/5

a = 80/5

a = 16m/s²
