Presentation transcript:

An air-track glider passes through a photoelectric gate at an initial speed of 0.25 m/s. As it passes through the gate, a constant force of 0.40 N is applied to the glider in the same direction as its motion. The glider has a mass of 0.50 kg. Draw a free body diagram of the forces and known variables from the problem.

Once you’ve drawn that… What is the acceleration of the glider? It takes the glider 1.3 seconds to pass through the 2nd gate. What is the distance between the two gates? The 0.40 N force is applied by means of a string attached to the glider. The other end of the string passes over a resistance-free pulley and is attached to a hanging mass (m). How big is m?
