Question

A body of mass 5 kg is moving with an acceleration of 2.5 m/s2. Calculate the force exerted on the body.​

Answer 1

Answer:

Explanation:

Mass =5 kg

Velocity =4m/s

Net force will be 0 . This is because an object moving with a uniform speed has zero acceleration, there is no change in velocity.

And according to Newton's second law of motion, we know, Acceleration is directly proportional to Force.

If acceleration =0

Force = Mass × Acceleration

Force = Mass × 0

Force = 0  

Thus, Net force acting on the body is 0.

Answer 2

Answer:

• Force exerted on the body is 12.5 N

Explanation:

Given

• Mass (m) = 5 Kg
• Acceleration (a) = 2.5 m/s²

To find

• Force (F)

Solution

⇰ F = ma

• F = 5 × 2.5
• F = 5 × 25/10
• F = 5 × 5/2
• F = 12.5

Hence, the force exerted on the body is 12.5 N
