Question

For the following problems, use a glider mass of 0.346 kg. 1. Atwood machine: A glider moves frictionless along a level air track, tugged by a vertically 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? Sloping air track: A glider moves frictionlessly along an air track that has been tilted by 1.5 inches over a span of 100 meters. What is the expected acceleration of the glider?

Explanation / Answer

1.
m_wg-T= m_wa ------1

T=.346a ----2

Equate equn 1 and 2

0.05*9.81-T=.05a

0.05*9.81-.346a=.05a

0.49=.396a

a=1.23

2.

ma=mgsin(theta)

a=9.0(1.5*2.54/100)

a=0.37 m/s^2
