A 4 .5kg object is observed to be moving with a velocity of 5 .0m/s @ 30 at t = 0. Later, at t = 75s, the object is observed to be moving with a velocity of 5.0m/s@30. (a) What is the change in momentum of this object in the time between the two observations? (b) What is the magnitude and direction of the average force on the object during those 75 seconds?
Answer and explanation please. Thank you so much
