Question

Two objects are connected by a massless string, as shown in the figure below. The incline and pulley are frictionless.

(b) Find the acceleration and tension for ? = 44° and m1 = m2 = 9 kg.
a = m/s2

Two objects are connected by a massless string, as shown in the figure below. The incline and pulley are frictionless. Find the acceleration of the objects. (Assume that positive acceleration is to the right form1 and downward for m2. Answer using m1, m2, g for the acceleration due to gravity, and ?.) a = a) Find the acceleration of the objects. (Assume that positive acceleration is to the right form1 and downward for m2. Answer using m1, m2, g for the acceleration due to gravity, and ?.) a Find the tension in the string. Find the acceleration and tension for ? = 44 degree and m1 = m2 = 9 kg.a = Find the acceleration and tension for ? = 44Â degree and m1 = m2 = 9 kg. Two objects are connected by a massless string, as shown in the figure below. The incline and pulley are frictionless.

Explanation / Answer

a). a = net force in the direction of motion/total mass => a = [m2*g - m1*g*sin(theta)]/(m1+m2) b). a = [9*9.8 - 9*9.8*sin(44)]/(9+9) = 1.496 m/s^2 let tension =T for mass m2, m2*g - T = m2*a => 9*9.8 - T = 9*1.496 => T = 74.736 N
