Question:

A force of \(10.0 \mathrm{~N}\) is applied at an angle of \(30^{\circ}\) to the horizontal on a \(1.25-\mathrm{kg}\) block initially at rest on a frictionless surface, as illustrated in Figure 4.14.

(a) What is the magnitude of the block's acceleration?

(b) What is the magnitude of the normal force? image text in transcribed
THINKING IT THROUGH. The applied force may be resolved into components. The horizontal component accelerates the block. The vertical component affects the normal force. (Review Figure 4.11 if necessary.) Drawing a free-body diagram for the block, as in Figure 4.14, is helpful.
