Question

Find the work done by a force 7=(7i+6K) N
displaces a body through 5 =(51+6j) m
1) 12 J 2) 24 J 3) 30 J 4) 35 J​

Answer 1

Answer:

............................

Answer 2

Answer:

35 J

Explanation:

For finding work, we have to use the dot product

W=F.s

F=(7i+6k)

s=(5i+6j)

W=7.5 i×i+0.6 j×j+6.0 k×k

W=35
