a constant force of 48 newtons was applied to a 16 kg mass for 7 seconds. what was the change in momentum of the mass

Respuesta :

Answer:

[tex]21 ms^{-1}[/tex]

Explanation:

Newton’s Second Law  

The rate of change of momentum of an object is directly proportional to the resultant force applied and is in the direction of the resultant force.

Let the change in velocity = V

[tex]force =\frac{mass*(velocity.difference)}{time} \\48=\frac{16*V}{7} \\V=21 ms^{-1}[/tex]
