Question

What is the mass of an object whose momentum is 35kg-m/s ..when its velocity is 7m/s​

Answer 1

5 kilograms

Step-by-step explanation:

Mass can be found using the following formula.

`m=(p)/(v)`

where p is the momentum and v is the velocity.

The object has a momentum of 35 kg m/s and a velocity of 7 m/s. Therefore,

p= 35 kg m/s

v= 7 m/s

Substitute these values into the formula.

`m= (35 kg- m/s)/( 7 m/s)`

Divide 35 kg m/s by 7 m/s. (35/7=5)

The m/s in the numerator and denominator cancel each other out.

`m= 5 kg`

The mass of the object is 5 kilograms.

Answer 2

5kg

Step-by-step explanation:

p = mv

m = p/v

m = 35/7

m = 5kg
