Question

The following figure shows a F = 5.0N force pushing two gliders along an air track. The 210g spring between the gliders is compressed. Assume the force F acts and the whole system moves in the same direction. The spring does not sag. (Figure 1) How much force does the spring exert on glider A? Express your answer to two significant figures and include the appropriate units. How much force does the spring exert on glider B? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

The total acceleration of te system is : 5/(0.21 + 0.4 + 0.6)

Asys = 4.1322 m/s^2

a)

Force by spring on A = 5 - 0.4 * 4.132 = 3.34 N

b)

Force by spring on B = 0.6 * 4.1322 = 2.47 N
