Question
A block of mass MA = 40 kg is placed on a wedge and connected by a light string over a massless pulley to a
second block of mass MB = 10 kg as shown. There is no friction anywhere. Find the acceleration of the block
B and the tension in the string, T.
(A) aB = 1.96 m/s? and T = 118 N
(B) aB = 2.94 m/s? and T = 118 N
(C) aB = 1.96 m/s² and T = 84.3 N
B
(D) aB = 2.94 m/s² and T = 84.3 N
30°
Two blocks connected by a light string and a massless, frictionless
pulley. There is no friction between block A and the surface of the
wedge.

Continuing with the previous problem, what is the speed of block A when it has slid down the incline 1.5 m?
(A) VA = 2.42 m/s
(B) VA = 2.71 m/s
(C) VA = 3.50 m/s
(D) VA = 4.30 m/s
(E) VA = 5.42 m/s
