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) Draw a diagram to show the go kart on the track and add an arrow to show the direction of the frictional force needed for the car to travel around the curve at a radius of 42 m. b) 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. c) Calculate maximum angular velocity at which the car can travel round the curve at a constant radius of 42 m.

hi is it possible for you to answer the attached please? i just need to check my current answers against someone elses, i dont mind final answers so i can compare and will ask more specific questions later if needed.

d) Calculate the maximum linear velocity. e) You decide that this is not nearly fast enough and decide to create a banked track of 12°, what is the maximum linear velocity now? f) Describe qualitatively how this could change if a child were driving the kart. g) It is important that the karts can brake effectively. They use drum brakes where a solid circular drum of mass 4.0 kg and radius 0.15 m is rotating at an angular speed of 22 rad s' about an axis when a 'braking' torque is applied to it which brings it to rest in 5.8 s. Calculate ) its angular deceleration when the braking torque is applied. i) the moment of inertia of the drum about the axis shown 1= =mr? i) the resultant torque that causes it to decelerate.
