let v is the speed of the blocks after moving 1.72 m
Apply conservation of energy
gain in kinetic energy = loss of potential energy
(1/2)*(m1 + m2)*v^2 = m2*g*d - m1*g*d*sin(33)
(1/2)*(18.4 + 12.75)*v^2 = 12.75*9.8*1.72 - 18.4*9.8*1.72*sin(33)
15.575*v^2 = 46
v = sqrt(46/15.575)
= 1.72 m/s <<<<<<<<--------------Answer

In a system, m1=18.4kg, m2 = 12.75 kg, and the angle = 33.0 degress. Assume that the pulley and the surface under m1 are frictionless. Please find the following: the acceleration and direction of the system. The initial potential energy of the system, before it moves 1.72m, and the the velocity of each mass after the system has moved by this distance.

Problem 3:
In an ordinary television set, the electron beam consists of
electrons shot horizontally at the television screen with a speed
of about 5 x 107 m/s. How far does a typical electron fall as it
moves the approximately 40 cm from the electron gun to the screen?
For comparison, how far would a droplet of water shot horizontally
at 2 m/s from a hose drop as it moves a horizontal distance of 40
cm?

Two blocks are attached to one another, as shown, by means of a massless cord that passes over a massless frictionless pulley. Block 1 (mass m1, = 10.0 kg) is connected to a spring with spring constant k = 100 N/m, and block 2 (mass m2 = 20.0 kg) sits on a frictionless ramp that makes an angle theta = 30.0 degree with the horizontal. The coefficient of kinetic friction between...
