## Homework Statement

A 2.00 kg block is held in equilibrium on an incline of angle = 75° by a horizontal force applied in the direction shown in Figure P4.50. If the coefficient of static friction between block and incline is µs = 0.300, determine the following.

(a) the minimum value of F

(b) the normal force exerted by the incline on the block

## Homework Equations

F=ma

## The Attempt at a Solution

For Y Component:

n-mgcos75=0

n=mgcos75

n=2.00*9.8cos75

n=5.07 N

It says this is wrong because of: Your answer differs from the correct answer by orders of magnitude.

For X

F-fs=0

F=usn=0

F=usn

F=0.300 x 5.07 N = 1.52 N

Does this look like I did it correctly?
