Question 8
The correct symbol to represent the speed of an object is
(a) 5 m/s
(b) 5 mp
(c) 5m/s−1
(d) 5 s/m
Speed=distancetime Speed=metersecond
So, Option (a) is the correct answer.
A plane mirror and an object approach each other with speeds of 5m/s and 10 m/s respectively. The speed of the image will be
A plane mirror and an object approach each other with speeds of 5 ms−1 and 10 ms−1 respectively. What will be the speed of the image w.r.t. the stationary observer?
