Question

Calculate the volume of a moving body of mass 5 kg whose linear momentum is 2.5 kgms-1

Answer 1

The correct Question:

Calculate the velocity of a moving body of mass 5 kg whose linear momentum is 2.5 kgms⁻¹

Answer:

momentum = p = mv

m = 5 Kg

p = 2.5

v =  $\frac{p}{m}$

v = $\frac{2.5}{5}$

v = 0.5 m/s

Answer 2

Correct question :-

Calculate the velocity of a moving body of mass 5 kg whose linear momentum is 2.5 kgms⁻¹.

Given :-

Mass of the body = 5 kg

Momentum of the moving body = 2.5 kgms⁻¹

To Find :-

The velocity of the moving body.

Analysis :-

Here, we are given with the mass and momentum of a moving body.

Substitute the given values in the formula of momentum and find the volume of the moving body accordingly.

Solution :-

We know that,

• p = Momentum
• v = Velocity
• m = Mass

Using the formula,

$\underline{\boxed{\sf Momentum=Mass \times Velocity}}$

Given that,

Momentum (p) = 2.5 kgms⁻¹

Mass (m) = 5 kg

Substituting their values,

2.5 = 5 × v

v = p/m

v = 2.5/5

v = 0.5 m/s

Therefore, the velocity of the moving body is 0.5 m/s.
