Question

A bird is flying north with a mass of 2.5kg has a momentum of 17.5kg m/s at what velocity is it flying

Answer 1

momentum = mass • velocity
v= 17.5/2.5
= 7 m/s

Answer 2

v=7 m/s

Step-by-step explanation:

momentum definition

The amount of movement or linear momentum is the product of velocity by mass. Velocity is a vector while mass is a scalar. As a result we obtain a vector with the same direction and direction as the velocity.

The magnitude of the momentum is calculated like this:

p=m*v Formula (1)

where:

p: momentum (kg*m/s)

m: mass (kg)

v: velocity (m/s)

Data

m = 2.5kg

p = 17.5kg m/s

Problem development

We replace the data in the formula (1)

17.5kg m/s = 2.5kg*v

`17.5 kg*(m)/(s) = 2.5kg * v`

`v=(17.5 kg*(m)/(s) )/(2.5 kg)`

v = 7 m/s
