Question

Two dogs, Rover and Fido, run on a level frictionless surface. River runs eastward with a momentum of 24 kg . m/s, and Fido runs northward with momentum 10 kg . m/s. They make a sudden perfectly inelastic collision. What is the magnitude of their combined momentum after the collision

Answer 1

26 kg x m/s

Step-by-step explanation:

Answer 2

The magnitude of their combined momentum after the collision is 26 kg-m/s.

Step-by-step explanation:

Given that,

Two dogs, Rover and Fido, run on a level frictionless surface.

Rover runs eastward with a momentum of 24 kg-m/s and Fido runs northward with momentum 10 kg-m/s. We need to find the magnitude of their combined momentum after the inelastic collision.

For inelastic collision, momentum remains conserved. The net momentum is given by :

`p=√(p_1^2+p_2^2) \\\\p=√(24^2+10^2) \\\\p=26\ kg-m/s`

So, the magnitude of their combined momentum after the collision is 26 kg-m/s. Hence, this is the required solution.
