Question 2 a)

A

ball rolls horizontally along a track. A camera takes a picture of the ball 4

times every second and the position of the ball at each photograph is shown in

the diagram below (note the leftmost ball position is the first photograph,

with each subsequent photograph showing the movement of the ball towards the

right of the track).

Which

of the graphs of position,

A car with a weight of 15,000N is being towed up a 20 degree slope at constant velocity. Friction is negligible. What is the tension in the tow rope?

Draw a free-body diagram to help you.

Give your answer to 0 decimal places in N. Do not include the units in your answer i.e. you would write 12 N as 12

A

car with a weight of 15,000N is being towed up a 20 degree slope at constant

velocity. Friction is negligible. The tow rope is rated at 6000 N maximum

tension. What are the forces acting on the car?

A car with a weight of 15,000N is being towed up a 20 degree

slope at constant velocity. Friction is negligible. What is the net force in

the x-component?

Give you answer to 0 decimal places in N. Do not include the

units in your answer i.e. you would write 100 N as 100.

Consider a bright fringe in a two slit interference pattern. If we look at this point and double the wavelength of the light used in the two slit experiment (such that it still produces a pattern) what happens to this point?

Which of the following equations correctly describes the wave speed on a string of mass M and length L under tension T?

Consider standing waves formed on a wire of length L under tension, fixed at both ends. Which of the following correctly describes the relationship between the lowest three frequencies f₁, f₂,and f₃, of the standing waves formed on the wire, if the wave speed on the wire is v?

Consider a standing wave on a wire under tension, fixed at both ends. Which of the following correctly describes the relationship between the displacement of a point on the wire to the speed with which that point moves?
