An object of mass 50kg is placed on inclined plane at an angle of 30 degrees to the horizontal. The height of the plane is 250cm and it's length is 500cm. What is the workdone in moving the object down the plane?
Answered by Damon
assuming no friction, gravity does all the work and it is the change in potential energy

m g h = 50 * 9.81 * .250 Joules

F=mgcos@= 50*9.81*sin30= 424.8N
H=250cm= 2.5m
W=F*h = 424.8*2.5= 1062 J

W= f*s*cos 50*1250*0.9=56250

F-mgsintheta=ma
Where F=force that tends to move it upward.
Mgsintheta= force that tends to move it downward.a=Acceleration
500-50×10sin30°=ma
500-250=50a
a=5m/s^2.
W=F×d=ma×d
50×5×500×10^-2
=50×5×5
=1250 Nm
