Suppose a constant force is the only force applied to an object of unknown mass. what quantities do we need to know in order to find the object's change in momentum? check all that apply. check all that apply. we need to know the change in the position of the object. we need to know the magnitude of the force. we need to know the time interval during which the force acts. we need to know the change in the velocity of the object. impossible: you cannot find the object's change in momentum without knowing its mass.

we need to know the time interval during which the force acts. impulse of force = momentum change

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
