Question

what is the acceleration of a body on a frictionless inclined plane whose height increased by 2m after every 4m of its length​

Answer 1

50 J

From FBD,

F=mgsinθ+f

or F=mg

x

h

+f as(sinθ=

x

h

)

or Fx=mgh+fx

or W

F

=mgh+W

f

as work done = force × distance.

150=5×10×2+W

f

or W

f

=150−100=50J

solution

expand
