There are two forces on the 1.19 kg box in the overhead view of the figure but only one is shown. For *F*_{1} = 15.7 N, *a* = 14.7 m/s^{2}, and θ = 34.1°, find the second force **(a)** in unit-vector notation and as **(b)** a magnitude and **(c)** a direction. (State the direction as a negative angle measured from the +x direction.)

Step 1

(a)

The expression for the second force from Newton’s second law,

Step 2

The expression for the total force in the *x *direction and* y* direction is,

Step 3

Substitute the ...
