Question

If the momentum of flying brick is 50 kg m/s and its mass is 10 kg.Calculate its velocity

Answer 1

Answer:

Explanation:

p=mv

50 kg m/s=10 kg ×v

50/10=v

5=v or v= 5m/s

Answer 2

Answer :-

5m/s

Explanation :-

Given :

Momentum of the flying brick,p = 50kg m/s

Mass of the brick,m = 10kg

To Find :

Velocity,v = ?

Solution :

We know Momentum (p) = Mass(m) × velocity(v)

$\sf{}\implies 50kg\ m/s =10kg\times v$

$\sf{}\implies v=\dfrac{50kg\ m/s}{10kg}$

$\sf{}\implies v=5m/s$

Thus,velocity of the brick = 5m/s

☆Additional Information☆

• Since,momentum is the product of mass and velocity (p = m × v) of an object.Therefore momentum increases with increase of either mass or velocity of an object.

• Momentum is directly proportional to the mass and velocity of an object.

• This means if lighter and a heavier object is moving with same velocity then heavier object will have more momentum than lighter one.

• Momentum of non-moving object is always 0,if an object is at rest it has no momentum

• SI unit of Momentum is kg m/s.
