Find Fn and a please. Use the steps outlined above to find the magnitude of the acceleration a of a chair and the magnitude of the normal force F_N acting on the chair: Yusef pushes a chair of mass m = 45.0 kg across a carpeted floor with a force F vector_p (the subscript p here is lowercase and throughout the question) of magnitude F_p = 170 N directed at theta = 35.0 degrees below the horizontal (Figure 1). The...
let Theta be an angle in quadrant IV with cos(theta)=3/5 find sin(2theta), cos(2theta) and tan(theta/2)
If cos theta= square root 11/6 and tan theta < 0, find the exact value of sin the 1. If cos os (0) – VII and tan(Q) <o, find the exact value of sino).
Experiments using "optical tweezers" measure the elasticity of individual DNA molecules. For small enough changes in length, the elasticity has the same form as that of a spring. A DNA molecule is anchored at one end, then a force of 1.5 nN (1.5 times 10^-9 N) pulls on the other end, causing the molecule to stretch by 5.0 nm (5.0 times 10^-9 m),as shown in the figure.(p.s. The source of the external force is the laser beam that traps and...
cot(theta)=-3/4 and cos(theta) 7. cot(0) - 3 4 and cos(0) <0, find the exact value of sec(0)
The critical angle is the largest angle for which the gravitational force does not yet cause the block to move. Finding the angle is a problem in which we deal with the block as a particle in equilibrium. Analyze Because the block is an inclined surface, the normal force perpendicular to the surface does not balance the downward force of gravity. The normal force and the force of gravity produce a net force that tends to slide the block down...
