Question

Suppose 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

517.5Ns

Step-by-step explanation:

F=(MV - MU)/t

where MV - MU is the change in momentum,

therefore, MV - MU = Ft

= 345 X 1.

= 517.5Ns
