help with Matlab

how do we use matlab to complete the following questions

A) Top speed of vehicle (analytical toolbox) We consider a typical sedan car, with the following parameters: mass m=1500kg, cross section area S=2.1m2, coefficient of drag Cd=0.27, rolling friction model: Fr=(0+1v)N where Fr is the rolling friction force, 0=0.0075 and 1=2104s/m,N is the reaction force and v is the speed of the car. The drag force can be computed using the formula D=21v2SCd a) Draw a free body diagram of the forces on the car b) Compute the drag and rolling friction forces when the car goes at a speed of v=27m/s(97kph) c) We want to compute the theoretical top speed of the car, for different engines with power outputs P=20kW(26.8hp),P=110kW(147hp). We assume that =20% of the power generated by the engine is lost in the transmission (thus, 80% of the power generated by the engine goes to the wheels) Hint: use the analytical toolbox to compute the speed, by solving a third degree polynomial. At constant speed, the power sent to the wheels is equal to the power dissipated by the drag and friction forces (P=(Fr+D)v)
