Question

A body starts from rest and moves with a uniform acceleration of 5m/s^2. What is its velocity after 10 seconds

Answer 1

✬ Final Velocity = 50 m/s ✬

Explanation:

Given:

• A body starts from rest (u) = 0
• Body moves with a uniform acceleration (a) = 5 m/s²
• Time (t) = 10 seconds

To Find:

• What is the final velocity (v) of the body after 10 seconds?

Formula to be used:

• First law of motion = v = u + at

Solution: Using formula

$\implies{\rm }$ v = u + at

$\implies{\rm }$ v = 0 + 5 x 10

$\implies{\rm }$ v = 0 + 50

$\implies{\rm }$ v = 50 m/s

Hence, The velocity of body after 10 seconds will be 50 m/s.

➪ S = ut + 1/2at²

➪ v² = u² – 2as
