Question

A net force F=5.00x newtons in the positive x direction acts on an object of mass 2.4kg for 5 meters.
A) what is the change in kinetic energy B) if the object were initially traveling at 30m/s in the negative direction what is its final speed C) what is the change in the momentum of the object A net force F=5.00x newtons in the positive x direction acts on an object of mass 2.4kg for 5 meters.

A) what is the change in kinetic energy B) if the object were initially traveling at 30m/s in the negative direction what is its final speed C) what is the change in the momentum of the object

Explanation / Answer

( C ) change in momentum = mass * change in velocity

                                        = m*(v-u)

                                        = 2.4*(30.06 - (-30 ) ) = 2.4*60.06

                                        = 144.144 kgm/s
