Question

A constant net force of 345 N is applied to slide a heavy stationary

couch across the floor. If the force is contact with the couch for 1.5 seconds,
then what is the change in momentum of the couch

Answer 1

P = 517.5 [kg*m/s]

Step-by-step explanation:

We must remember that momentum is defined as the product of force by the time of force duration.

`P=F*t`

where:

P = momentum [kg*m/s]

F = force [N]

t = time [s]

`P=345*1.5\\P=517.5[kg*m/s]`
