Answer:
(a) 19.62 N
(b) Box moves down the slope
(c) 24.43 N
Explanation:
(a)
2 Kg box causes tension
hence
where m is mass and g is gravitational force
T'=4*9.81 sin 35= 22.5071 N
Since T' is greater than , then the box moves down the slope
(c)
Acceleration a=
When moving, the box will exert force T"=
T"= 4*9.81 sin 35 +(4*0.48)= 24.43 N
