Question

What a the momentum of a 3.5-kg boulder rolling downhill a 5 m/s

Answer 1

p = mv
p = 3.5 × 5
p = 17.5 kg .m/s

Answer 2

Answer : The momentum of an object is,
`17.5\text{ Kg }m/s`

Solution : Given,

Mass of an object = 3.5 Kg

Velocity of an object = 5 m/s

Momentum : Momentum is the product of mass and the velocity of an object.

Formula used :

`p=m* v`

where,

p = momentum of an object

m = mass of an object

v = velocity of an object

Now put all the given values in this formula, we get the value of momentum of an object.

`p=(3.5Kg)* (5m/s)=17.5\text{ Kg }m/s`

Therefore, the momentum of an object is,
`17.5\text{ Kg }m/s`
