2. What is the name of the force acting on the car as it drives in a circle? A. Centrifugal B. Central C. Centripetal
3. The Correct answer is C! A centripetal force acts perpendicular (at a right angle) to the direction of motion of the car as it travels in circular motion.
4. Which value for the co-efficient of friction will make the object more difficult to move? A. 1.5 B. 1 C. 0.01 = Hint: Try plugging in some values to the equation and see how large the frictional force is for each
5. The Correct answer is A! The co-efficient of friction µ (mu) is a dimensionless number that tells us how large the frictional force between two materials will be. The larger the value of µ the larger the size of the frictional force. =
6. What is the minimum value for the radius of corner so Lewis Hamilton is able to drive at 30 Ms-1 around the corner? µ = 1.5 and g = 9.8Ms-2 A. 61.2 m B. 60.5 m C. 612 m = Hint: Think about which variable we need in the equation above
7. The Correct answer is A! First re-arrange the equation such that r is the subject of the formula, then plug in the values given, this should yield the correct result of 61.2m
