i rili have no idea :s this is a question from my textbook, and they give no explanation
Phosu:
the acceleration u calculated is rong
42=2xax16
16/32=a
a=0.5

OMG ure write.
cant believe, i'm making dumb mistakes,wit exams coming up in a week.
halosh92:
a particle A of mass 2.5kg which is at rest on a smooth inclined plane of angle 25 is connected to a particle B of mass 1.5kg by a light inextensible string which lies along a line of greatest slope of the plane and passes over a fixed smooth pulley at the top of the plane. B hangs freely and the system is released from rest with the string taut. find the acceleration of the system and the tension in the string. if the angle of inclination of the plane is increased to 45 find the new acceleration.
just how to do the part in red ??
