In Part B of the examination you must show all your work. Answer all these questions in the answer booklet. Show all the work needed to solve the problem: data given, explanations, formulas and calculations. Then write your answer in the space provided. You will be given no marks if you provide the right answer without showing your work. However, you will be given part marks for work that is partially correct. Where necessary, corrections will take into account the units of measurement.

A plastic right-angled isosceles triangle is placed on the bottom of the tank so that the short sides are parallel to the tank’s walls. The laser’s beam is refracted to point B, a 1.75 cm deviation from point A (Diagram 2). The beam leaves the triangle from a point 20.0 cm away from point A. What is the index of refraction of the plastic triangle?

A police officer was sitting in his stationary patrol car waiting to catch a speeding vehicle. A car passed the officer at a speed of 72 km/h. The instant it passed, the officer accelerated uniformly to 90 km/hour in 10 seconds and continued at that speed until he caught the speeding vehicle. How far had both vehicles travelled when the officer caught up with the speeding car?

A Fapplied = 6.6 N

0.15 kg Slider

Ff = 0.11 N

The top of the "hump" is 1.2 m above the level of the slider at the beginning of the track. The average force of friction between the 0.15 kg slider and the track is 0.11 N. The distance from point A to point B along the track is 2.3 m. Yue’s brother propels the slider by applying a constant force of 6.6 N hoping to get it over the "hump". How far must he push the slider to ensure that it makes it over the "hump"
