Question

A body of mass 10 kg is moving with a velocity of 5 m/s attainsvof 35m/s in 5 second find the force applied on body to change its velocity

Answer 1

Here, as per the provided question we are asked to find the force applied on a body to change its velocity -

GIVEN :

• Mass of a body = 10kg
• Moving with the velocity (initial) = 5m/s
• Final velocity = 35m/s
• Time period covered = 5s

TO FIND :

• Force applied on body to change its velocity = ?

STEP-BY-STEP EXPLANATION :

Now, we will have to find the force applied on the body to change its velocity ,·–

Formula Used :

• v = u + at

→ [ Substituting the values ]

→ 35 = 5 + a × 5

→ 35 - 5 = 5a

→ 30 = 5a

→ a = 30/5

→ a = 6m/s²

Therefore, acceleration = 6m/s²

Formula Used :

• F = ma (mass × acceleration)

→ [ SUBSTITUTING THE VALUES ]

→ F = 10 × 6

→ F = 60n

Force = 60Neuton ✔️.
