Question
The trolley has a mass of 0.75 kgCalculate the acceleration of the trolley just after it is released.Give the unit._____________________________________________________________________________________________________________________________________________________________________________________________________________________________Acceleration = ____________________ Unit (4)An elastic cord is fixed to the trolley.Figure 2 shows the arrangement viewed from above.Figure 2When the trolley is pushed and released a wave travels along the cord.(c) What type of wave travels along the cord?___________________________________________________________________Give the reason for your answer.(2)Page 14 of 51Waves (F)
Solution
The question seems to be incomplete. For calculating the acceleration of the trolley just after it is released, we need more information such as the force applied or the angle of the slope (if any).
As for the type of wave that travels along the cord when the trolley is pushed and released, it would be a transverse wave. This is because the displacement of the medium (the cord) is perpendicular to the direction of the wave. In a transverse wave, the particles of the medium move up and down while the energy of the wave moves forward. This is what happens when a wave travels along a cord or a string.
