not depends on t or directly proposal to T^0
parul83:
options are a- v is directly proportional to t^3/2 b- v is directly proportional to t c- v is directly proportional to t^1/2 d- v is directly proportional to t^-1/2.
sry... v=-/''2pt/m so the answer is t^1/2
I m very sry for giving the ans wrong 1st time

Answer:c
Explanation:power = joules / time
P=mv^2 / 2t
v^2 = 2Pt / m
v = (2Pt / m)^1/2.
Option c
