An 2 kg object moving at a velocity of 5 m/s decelerates at a rate of 0.8 m/s^2. How long will it take the object to achieve a change of momentum of 6 kg x m/s?
3.75 seconds (there are different ways of calculating this)
1. 6 kgxm/s = 1.6 N (time), solve for time
2. 2 m/s = 5 m/s + (-0.8 m/s^2)t, solve for time
