3. PRELAB QUESTIONS or the Atwood machine apparatus, draw two free-body diagrams which clearly indicate the forces acting on: 1. F i. The glider ii. The hanging mass For the following problems, use a glider mass of 0.346 kg. 2. Atwood machine: A glider moves frictionlessly along a level air track, tugged by a ver- tically suspended mass of 0.050 kg that is attached to the glider with a string that is looped over the pulley (refer Figure 5). What is the expected acceleration of the glider? 3. Sloping air track: A glider moves frictionlessly along an air track that has been tilted by 1.5 inches over a span of 1.00 meters. What is the expected acceleration of the glider?

Explanation / Answer

Given,

Mg = 0.346 kg ; m = 0.05 kg ;

T = Mg a = 0.346 a

mg - T = ma

0.05 x 9.81 - 0.346 a = 0.05 a

a (0.346 + 0.05) = 0.4905 => a = 1.24 m/s^2

Hence, a = 1.24 m/s^2

3)tilt = h = 1.5 in = 0.0381 m

sin(theta) = 0.0381/1

m a = m g sin(theta)

a = g sin(theta) = 9.8 x 0.0381 = 0.37 m/s^2

Hence, a = 0.37 m/s^2
