Question

The velocity of an object increases from 20 m/s to 40 m/s in 10 second. Find the acceleration of that object

Answer 1

Answer:

Hey Mate!!

Given,

u = 20 m/s

v = 40 m/s

t = 10 s

v = u + at

••> 40 = 20 + 10a

••> 40 - 20 = 10a

••> 20 = 10a

••> a = 20 ÷ 10

••> a = 2 m/s^2

Answer 2

Answer:

2 m/s²

Explanation:

Initial velocity = 20 m/s

Final velocity = 40 m/s

Hence, change in velocity = (40-20) m/s = 20 m/s

Time = 10 s

Acceleration = (20/10) m/s² = 2 m/s²
