Answer:
v=7 m/s
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
[tex]17.5 kg*\frac{m}{s} = 2.5kg * v[/tex]
[tex]v=\frac{17.5 kg*\frac{m}{s} }{2.5 kg}[/tex]
v = 7 m/s
