Question 3 - use this information to answer the following two questions: Three forces act on a moving object. One force has a magnitude of 60.0N and is directed due North. Another has a magnitude of 90.0N and is directed at angle 45 South of East (a) What must be the magnitude of a third force such that the object continues to move with constant velocity? (b) What is the direction (angle with respect to the East direction) of the third force? Question 4 3 pts Three forces act on a moving object.

Question 5 2 pts Three forces act on a moving object. One force has a magnitude of 60.0N and is directed due North. Another has a magnitude of 90.0N and is directed at angle 45 South of East (b) What is the direction (angle measured counterclockwise from the East direction) of the third force? Answer is a positive number
