Question

$\huge \bf Question →$What's the force required to move a body of mass 5 kg with a constant acceleration of 2.5 m/s²​

Answer 1

Explanation:

Given,

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

$\qquad \underline{\red {\sf Given }}$

• Mass = 5 kg

• Acceleration = 2.5 m/s²

$\qquad \underline{\red {\sf To \: Find }}$

• Force

$\qquad \underline{\red {\sf Formula \: Used }}$

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

$\tt : \implies 5\times 2.5$

$\tt : \implies \cancel{5\times \dfrac{25}{10}}$

$\tt : \implies \dfrac{25}{2}$

$\bf : \implies 12.5$

Thus, the force required is 12.5 N
