Question

Calculate the net force acting on a body of mass 40 kg moving with a uniform velocity
of 2ms-1​​

Answer 1

Explanation:

What force is required to move a body of mass 1kg with a uniform velocity of 1m/s? ∴ F=ma=zero, i.e., no force is required.

Answer 2

Given :-

Mass of the body = 40 kg

Velocity of the body moving = 2 m/s

To Find :-

The net force acting on the body.

Solution :-

We know that,

• a = Acceleration
• f = Force
• m = Mass

According to the question,

Mass (m) = 40 kg

Acceleration (a) = 0 m/s

By using the formula,

$\underline{\boxed{\sf Force=Mass \times Acceleration}}$

Force=Mass×Acceleration

⇒ force(m) = 40 × 0

⇒ force(m) = 0 N

Therefore, the net force acting on the body is 0 N.
