Question

A moves 10m towards north in 8 sec, and then 20m towards west in 5 seconds with what velocity should move
in the direction towards the final point from the initial point. So that he reaches the final point in equal time​

Answer 1

Answer:

$\frac{10 \sqrt{5} }{13} m {s}^{ - 1}$

Explanation:

Net displacement =

$\sqrt{ {10}^{2} + {20}^{2} } = \sqrt{500} = 10 \sqrt{5}$

Net time taken=8+5=13

So;Required velocity=

$= \frac{disp.}{time} \\ = \frac{10 \sqrt{5} }{13}$
