Question

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The object m1 is held at rest on the floor, and m2 rests on a fixed incline of ? = 43.0

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley as in the figure below. The object m1 is held at rest on the floor, and m2 rests on a fixed incline of ? = 43.0degree. The objects are released from rest, and m2 slides 1.00 m down the incline in 3.70 s.

Explanation / Answer

accelaration of the system a= [m2 sin(43)-m1]*g/(m1+m2).... a=1.619 m/s^2.....for m1 in upward and for m2 is downward B)T=m1(a+g)=4(1.619+9.8) =45.64 N...... C)0.932
