Is someone able to help me with the following?

ilinestion 2 Go Kart Track{AC'1.1, 1.2, 3.1, 3.2, 5.1 3; 5.2} Your go karts have a mass of 4kg and travel around a circular curve on a at, 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 of42 m. h] The maximum frictional force between the tyres and the road is equal to 20% of the weight of the car and driver. Calculate the coefcient of friction when an adult of mass Tkg 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. Equation Defined symbols w = _ w = angular velocity (rad s - 1) 0 = angle (rad) verw t = time (s) Aw At v = linear velocity (ms-1) a = ra a = angular acceleration (rads-2) w1 = w2+ at r= radius in meters (m) F = mv2/r a = linear acceleration (ms-2) F = mrw2 W.d. = work done (J) W.d. = TO T = torque Power = TW I = moment of inertia (Kgm?) W = 2TTr / T o= stress (Pa) T = Fr = la & = strain (dimensionless) O = F/A A = cross sectional area (m?) E = X/I I = original length (m) E = O/ E. x = extension F= UN E = Young Modulus Q = mcAT F = (frictional) force (N) Q = mL H = coefficient of friction (dimensionless) N = normal reaction force (N) Q = Energy transferred (J) M = mass (kg) c = specific heat capacity (JKg-1.C-") L = latent heat (J) AT = change in temperature (C)
