Question
Hi Can you please help me solve D and E?
Question 2 – Go Kart Track Your go karts have a mass of 450kg and travel around a circular curve on a flat, horizontal track at a radius of 42 m.
A) The maximum frictional force between the tyres and the road is equal to 20% of the weight of the car and driver. Calculate the coefficient of friction when an adult of mass 70kg is driving the kart.
B) Calculate maximum angular velocity at which the car can travel round the curve at a constant radius of 42 m.
C) Calculate the maximum linear velocity.
D) You decide that this is not nearly fast enough and decide to create a banked track of 12O, what is the maximum linear velocity now?
E) Describe qualitatively how this could change if a child were driving the kart.
For A I have an answer of 0.2
For B I have 0.218 rad/sec
For C I have 9.156 m/s
If I have these wrong it would be useful to see where if possible.
