All Mechanics DOUBTS HERE!!!
dk bose:
1)A body of mass 5kg is held in equilibrium under gravity by two inextensible light ropes.One rope is horizontal,the other is at an angle teetha to the horizontal,as shown in the attachment.The tension in the rope inclined at teetha to the horizontal is 72 N.
(a) the tension T in the horizontal rope giving ur ans to the nearest N.
2)A small sphere R,of mass 0.08kg,moving with speed 1.5m/s,collides directly with another small sphere S,of mass 0.12kg,moving in the same direction with speed 1m/s. Immediately after the collision R and S continue to move in the same direction with speeds U m/s and V m/s respectively.
Given that U:V=21:26,
(a) show that V = 1.3,
(b) find the magnitude of the impulse, in Ns, received by R as a result of the collision.

Its been a long time since I did my M1, I did the first question for you, as for the second, :X
astarmathsandphysics:
my answer to two questions above
dk bose:
my doubts,the circled ones.!!!
astarmathsandphysics:
No can do now. Nov exams tomorrow and I have a 24 day ahead. Will do Tues morn
