Calculate the magnitude of the total resultant force Fr = F1 + F2 + F3 acting on the mass.
What angle does Fr make with the positive x axis?
What is the magnitude of the mass’s acceleration vector, a?
What is the direction of A? In other words, what angle does this vector make with respect to the positive x axis?
How far (in meters) will the mass move in 5.0 s?
What is the magnitude of the velocity vector of the block at t = 5.0 s?
In what direction is the mass moving at time t = 5.0 s? That is, what angle does the velocity vector make with respect to the positive x axis?
Part A = 6.70 s
Part B = 5.59 s
