A plane lands at 260 kms per hr.

The mass of the plane is 400 tons.

All 16 rear wheels contact ground at the same time.

The lift of plane at the moment of touch down is 95% of plane's wight.

The coefficient of kinematic friction between the runway and its wheels is 0.5

The mass of one wheel is 125 kg and its radius of gyration is 0.75 m. The radius of a wheel is 1 m.

1. How far would the wheels skid before they begin to roll without slipping?
2. What's the skidding time?
3. What is the deceleration of the aircraft while it's skidding?
4. What is the energy dissipated as heat due to friction?
