P is facing a plane mirror while Q is running towards him from behind. If Q is running at a speed of `"3 m s"^(-1)`, how fast does Q appear to be running towards P in the mirror?

A

`"1 m s"^(-1)`

B

`"2 m s"^(-1)`

C

`"3 m s"^(-1)`

D

`"4 m s"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C

When man Q runs at a rate of `"3 m s"^(-1)` towards man P, his image will also be seen running out of the mirror at 3 m every second.

Two skaters P and Q are skating towards each other. Skater P throws a ball towards W every 5 s such that it always leaves her hand with speed 2 ms^(-1) with respect to the ground. Consider two cases: (I) P runs with speed 1 ms^(-1) towards Q while Q remains stationary (II) Q runs with speed 1 ms^(-1) towards P while P remains stationary. Note that irrespective of speed of P, ball always leaves P's hand with speed 2 ms^(-1) with respect to the ground. Ignore gravity. Balls will be received by Q .
