Help needed in statistics ! Thanx :)

system The crate shown is held against wedge B by a spring Part A Determining the normal force exerted by the crate on the wedge Determine the normal force Nc that the crate exerts on the wedge when the system is at rest. Express your answer to three significant figures and include the appropriate units The spring is 94.0% of its original uncompressed length 3.00 m, and the spring constant is given as k 1650 N/m. The coefficient of static friction at all contacting surfaces is 14-0.110. The mass of Hints the crate is m = 27.0 kg . The angle is 13.00 Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move Nc =1 Value Units Figure 1 |ofl Submit My Answers Give Up Part B Finding the smallest horizontal force P to move the crate upward Determine the magnitude of the smallest horizontal force P that is necessary to begin moving the crate upward Pati ecary bar Express your answer to three significant figures and include the appropriate units. Hints P-Value Units

Explanation / Answer

a)

Spring Compression

x=3-3*0.94=0.18 m

Normal force due to crate on the wedge

NC=mg+kx=27*9.81+1650*0.18

Nc=561.87 N

b)

smallest Horizontal force P to move crate upward is

P=Ncsin13+u*Ncos13 =561.87(sin13+0.11cos13)

P=186.6 N
