Question

a body of massb20kg slides down a plane inclined at 30degree to the horizontal if a constant resting force of 40N act on the body it acceleration down the plane is what?
 f=mgsin
 ma=mg sin 
 20×a=20×10sin30
 20a=100
 a=50

See previous post.

favour · Answer

using F=MA, Mg=Mgsin in Relation we have;- M=20kg, F=40N, a=? :-(a) as subject formula, :- a=f/m, 40/20=2 mgsin= 2*10sin, 20sin30degree 10.
