Question
A trolley is moving horizontally with a constant velocity of v m/s w.r.t earth A man running from one end of the trolley a velocity 1.5 vm/sw.r.t. to trolley. After reaching the opposite end, the man return back and continues running with a velocity of 1.5 vm w.r.t. the trolley in the backward direction . If the length of the trolley is L then the displacement of the man with respect to earth during the process will be : -
Options
A.2.5 L
B.1.5 L
C.
D.
Solution
For man on trolley 
vt = L ⇒ t = 
with respect to ground : vt +
vt = L + 
= 
∴
vt - vt = L - 
∴ ᐃS = 
- 
= 
vt = L ⇒ t = with respect to ground : vt +
vt = L + = ∴
vt - vt = L - ∴ ᐃS = - = Create a free account to view solution
