Question

the linear momentum of a ball of mass 50 gram is 0.5 kilogram metres per second find its velocity ​

Answer 1

Answer:

P = mv

=> v = P/m = 0.5/(50x10^-3) = 10 m/s

Answer 2

Answer:

The velocity of the ball is 10 m/s.

Step-by-step explanation:

Given:

Linear momentum of the ball (p) = 0.5 kg m/s

Mass of the body (m) = 50 g

Convert gram into kilogram

As we know, 1 kg = 1000 g

So, $\frac{50}{1000}$

→ 0.05 kg

Now, mass of the body is 0.05 kg

To find:

Velocity = ?

Solution :

Linear momentum = Mass x velocity

So,

Velocity = $\frac{Linear Momentum }{Mass}$

$= \frac{0.5}{0.05} m/s$

$= 10m/s$

Therefore, the velocity of the ball is 10 m/s.

What is velocity?

• The velocity of a body is the distance travelled per second by the body in a specified direction.

• The S.I unit of velocity is metre per second (m/s).

• The C.G.S unit of velocity is centimetre per second (cm/s).
