Which two formulae relate force to momentum?

(Select all that apply)

A 20 kg object was initially moving at 10 m/s. It is now moving at 25 m/s.

Calculate the object's change in momentum.

An 5 kg object was initially moving at 6 m/s. It is now moving at 20 m/s. This change took 2 s.

Calculate the magnitude of the force that caused this change.

A 100 N force caused an object to increase its momentum by 50 kg m/s.

How much time did it take for this change in momentum to occur?

In a vehicle crash, the momentum of the people inside quickly decreases to zero.

Lengthening the time of this momentum change will decrease the forces acting upon the people in the vehicle.

Which safety features of a car aim to slow the rate at which momentum is lost?
