Question

A planes velocity changes from 0 m/s to 60 m/s in 20 seconds. What is its
acceleration?
3 m/s2

3 m/s

0.3 m/s2

0.3 m/s

Answer 1

Answer:

Option A. 3 m/s2

Explanation:

Given data: Initial velocity = 0 m/s

Final velocity = 60 m/s

Time taken = 20 seconds

Required : acceleration = ?

Solution: We know that

Acceleration = final velocity - initial velocity / time taken

Acceleration = 60 m/s - 0m/s ÷ 20 s

Acceleration = 60 m/s ÷ 20 s

Acceleration = 3 m/s2

So the acceleration produce in the body is 3 meter / second square.
