Right answer is 2 sec.
a = m2 x g / (m1+m2).
= 3.2 x 9.81 / (6.6+3.2),
= 3.203,
s = ut+0.5 at^2.
t = 1.18 ~ 2.
a = m2 x g / (m1+m2).
= 3.2 x 9.81 / (6.6+3.2),
= 3.203,
s = ut+0.5 at^2.
t = 1.18 ~ 2.

How to calculate initial speed of mass, in equation of motion?

First, we have to calculate the Acceleration which is;
a = g(m1-m2$)/(m1+m2).
Where $ is used to denote the coefficient of friction equal to 1/3.
a = 1m/s.
Use equation s = vt + 1/2at^2
Vi = 0.
t = 3 sec.
a = g(m1-m2$)/(m1+m2).
Where $ is used to denote the coefficient of friction equal to 1/3.
a = 1m/s.
Use equation s = vt + 1/2at^2
Vi = 0.
t = 3 sec.
