A gardener pulls a roller along the ground through a distance of 20 m.if he applies a force of 20 kg wt in a direction inclined at 60 degree to the ground.find the work done by him (take g=10m\s )

Answer 1

20 kg wt = 200 Newtons
Force Component along ground
= 200*cos 60 = 100 N
Work = 20 * 100 = 200 J

Answer 2

20 kg wt = 200 Newtons
Force Component along ground
= 200*cos 60 = 100 N
Work = 20 * 100 = 2000 J

Answer 3

20kgwt=200N, w=fscos60,, W=200*20*1/2. . w=2000j

Answer 4

W=Fscos$ where $ is angle
W=20×10×20×1/2=2000J
