Question
. Answer only two of the following three questions
1 System consists of two particles with mass 2gm with positions and velocities as follows:
r₁=i-2j-k
r₂ = i + k
v₁ = i- j + k
v₂ =j+ k
Draw particles position and Find the kinetic energy of the system; and then compare it
with the value of kinetic energy of the system center of mass.
2 A body of mass m was initially at rest. A constant force Fo acted on it for a time to; then
suddenly the force tripled to 3Fo. Find the total distance the body travels in a time 2to,
and the net acceleration of this body.
3 An Atwood machine consists of two weights of mass 4kg and 8kg connected by a light
inextensible cable of length 1m which passes over a pulley. Find the acceleration of the
machine, discuss your result.
