Question

a train is moving with speed 30km/hr toward east & cycle towards south with speed 10km/h
find:- velocity of train w.r.t cycle & direction​

Answer 1

Answer:

what is the time here say properly

Answer 2

Answer:

20km/h or 5.56m/s

Explanation:

V be velocity of train and v be velocity of cyclist then

V'(V W.R.T v) is relative velocity

since V=30km/h=8.33m/s. ( toward east)

v=10km/h=2.78m/s. ( toward south)

=-2.78m/s. (toward east)

V'=V+(-v)

V'=8.33-2.78

V'=5.56m/s or 20km/h
