Question

Calculate the acceleration of a body if it starts from rest and attains the velocity 20 ms⁻¹ in 10 seconds.

Answer 1

hey dear
here is your answer ☞

==============

⭐ here, u = 0
v = 20 m/s
t = 10 s

a = v-u/t
=> 20-0/10
=>2 m/s² ⭐

hope it helps ^_^

Answer 2

In order to calculate the acceleration of the body,

Acceleration = (final velocity – initial velocity)/time

Here, final velocity = 20 m/s, initial velocity = 0 m/s and time = 10 seconds

Acceleration = (20 – 0)/10

A = 20/10 = 2 m/s^2

Hence, the acceleration of the body with this situation will be 2 m/s^2
