Question

A ball of mass 3.2 kg is placed in a wedge, as shown in the figure, in which the two walls meet at a right angle. (Figure 1) Determine the magnitude of contact force 2. Express your answer using two significant figures.

Explanation / Answer

Angle between F2 and gravity = 45 - = 45 - 20 = 35 deg

F2=mgcos( 45- ) = mgcos35 = 3.2*9.8*cos35 = 25.7 N
