Question
A particle is resting on a smooth horizontal floor. At t = 0 , a horizontal force starts acting on it. Magnitude of the force increases with time according to law F = α . t , where a is a constant. For the figure shown which of the following statements is/are correct ?
Options
A.Curve 1 shows acceleration against time
B.Curve 2 shows velocity against time
C.Curve 2 shows velocity against acceleration
D.none of these
Solution
F = at
a =
t ....(i) straight line curve 1
dv =
tdt
v =
curve 2....(ii)
divide (ii) by
v =
→ Paacebole curve 2.
