Two blocks connected by a cord passing over a small, frictionless pulley rest on

Question

Two blocks connected by a cord passing over a small, frictionless pulley rest on frictionless planes. (m1 = 110 kg, and m2 = 45 kg. Assume positive accelerations to be up and to the right for the left hand block, down and to the right for the right hand block.)

(a) Which way will the system move when the blocks are released from rest?

(b) What is the magnitude of the acceleration of the blocks?
......... m/s2

(c) What is the tension in the cord?
........N

Assume positive accelerations to be up and to the right for the left hand block, down and to the right for the right hand block.) (a) Which way will the system move when the blocks are released from rest? The blocks won't move. The blocks will slide to the left. The blocks will slide to the right. (b) What is the magnitude of the acceleration of the blocks? ......... m/s2 (c) What is the tension in the cord? ........N do it step by step abd show all of your work

Explanation / Answer

let m1 moves down

then
we get equations

110*9.8 sin30 - T = 110*a

T - 45*9.8*sin53.1 = 45*a

adding both we get

magnitude of accelration =a= 1.202 m/s^2

m1 is moving down and m2 moving up

T = 406.75 N
