The gauge prerssure in both the tyres of a bicycle is `7.0 xx 10^5 Pa` If the bicycle and the person riding it have a combined mass of 100 kg. find the area of contact of each tyre with ground.Use `g = 10 ms^(-2)`

the gauge pressure in both tyres of a bicycle is 690 k Pa. If the bicycle and the rider have a combined mass of 90 kg. what is the area of contact of each tyre with the ground? (assume that each tyre supports half the total weight of the bicycle.)

A cyclist rides round a curved path of radius 10m at a speed 18 kmph. If the cycle and the rider together have a mass of 100 kg, the firctional force the ground exerts on the wheel is (g = 10 ms^(2) )

Find the work done of move an object of mass 3 kg to a height of 20 m from the ground (Take g =10ms^(-2) ).

A pile driver of mass 200kg falls vertically through 3.2m on to pile of mass 600kg .Which it drives into the ground through a distance of 0.08m. If the pile driver remains in contact with pile after collision.Find the resistance offered by the ground . (g=10ms^(-2))
