Question

Figure 5.3: Diagram of the impuise experiment. A car falls down the air track from a height h. The track is inclined at an angie by placing a block of thickness y under ane of the legs of the track. The car is released a distance L from the ferce transducer, which is placed at the bottom of the track. Collision derivation problem. A car is released from rest on a frictionless inclined plane (Figure 5.3). EXAMPLES: Calculate the momentum pi at the end of the plane in terms of the measured quantities x, y, L, and m. Assume θ is very small so that h/L is approximately equal to y/x. (Hint: use conservation of energy and the fact that K 1/2mv2 p/2m.) Answer P1 - m If a car suffers a nearly elastic collision it will coast back up the ramp a distance Lf before reversing direction. What is the momentum Pr immediately following the collision? The general expression for the change in momentum suffered in a collision is A is A ' What is Δ p (the magnitude of Δ ) in terms of x, y, L, Lf, and m? This is the expression you should use in the experiment. Make sure you understand how to derive these equations. QUESTION If the car has a mass of 0.4 kg, the ratio of height to width of the ramp is 11/125, the initial displacement is 2.2 m, and the change in momentum is 0.86 kg*m/s, how far will it coast back up the ramp before changing directions?
