Answer q1c. Qa was sent previusly if you need to refer to any calculations (a) The mass of a car is 1342 kg. Its semi-wheelbases a₁ and a₂are respectively 1.51 and 1.10 m, without passengers. When 2people get in, the position of the centre of mass shifts forwardby 4 cm. The occupants have the same mass and they areseating in the front seats.If the overall load on the front axle of the car is 6420 N, what isthe weight of each passenger?(c) The two people seen in (a) are using the vehicle to perform aleft turn, with yaw rate 20 deg/s, u=55 km/h, v=1.84 km/h. Thevehicle front and rear tracks are the same, 1.5 m.Calculate the value of the vehicle sideslip angle (in deg).Calculate the value of the sideslip angle at each wheel centre(in deg), using a clear notation.
