Question

Zero is a point on ground chosen as origin of first body surfers the displacement of 10 root2 m north east next 10 m North and finally 10 Route 2 m is not West how far is it from the origin

Answer 1

Hii dear,

# Answer- 30 m

# Explaination-

Looking at the diagram, body moves in directions A-B-C-D.

Now, we know,

AB = 10√2 m

BC = 10 m

CD = 10√2 m

sin 45 = l1/AB

1/√2 = l1/10√2

l1 = 10 m

l2 = BC = 10 m

sin 45 = l3/CD

1/√2 = l3/10√2

l3 = 10 m

Total distance = l1+l2+l3

l = 10+10+10 = 30 m

Hope this is helpful...
