sqme as of speed 50cm/sec

rreed8249: nope bro it would be 100 cm/ sec ..

For PLANE mirror,

v = -u

Diff it wrt time, we get:
Vel. of Image wrt mirror = - Vel. of object wrt mirror
⇒V(i,m) = -V(o,m)
[V(i)-0] = - [ 50-(0)]
V(i)= -50 cm/sec..
V IMAGE wrt OBJECT = V(i)-V(o)
=-50-50=-100 cm / sec

rreed8249: Hope u understood it..

PBrain: hey

PBrain: wrt and diff means

rreed8249: wrt means with respect to and diff means differentiate

PBrain: ok

PBrain: hey I marked you as brainlist
