Please hand written answer and hopefull solutions.

The bike is moving at a speed of 3 m/s. The box(solid cuboid) is placed and fixed on bike saddle, having mass of 8 kg and dimensions of height h=0.15m, width w=0.23m and depth d=0.28m. The person driving the bike instantly press the front brake so there is no motion in front wheel and rear wheel starts to lift of the ground. Both bike and box starts to rotate around point A which is in contact with the ground. The distance between point A and bike saddle is 1.3 meters.

a)Calculate the moment of inertia around point A where is wheel in contact with the ground.

b)Calculate the kinetic energy and work done when front brake is applied

c)And calculate power
