A mosquito net over a 7ftxx4ft bed is 3 ...

A mosquito net over a `7ftxx4ft` bed is 3 ft high. The net hs a hole at one corner of the bed through which diagonally opposite upper corner of the net. A. Find the magnitude of the displaceentof the mosquito. B. Taking the hole as the origin, the length of the bed as the X-axis, its width as teh Y-axis, and verticallup as the Z-axis, write the components of the displacement vector.

Text Solution

Verified by Experts

The correct Answer is:
(a) `sqrt(74)` ft (b) component of the displacement vector are 7ft and 3ft

Displacement vector, ` vecr=7hati+4hati+3hatk,`

(a) Magnitude of displancement `sqrt(7^2+4^2+3^2), sqrt(74) ft`, (b)Component of the displacement vector are 7 ft, and 3 ft,.
