Force exerted by a truck is 500000N and the pressure on the ground is 2500000Pa. Calculate the area of contact of tyres with ground?

The pressure exerted on the ground by a man is greatest

the gauge pressure is 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.)

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)

Find the pressure exerted by a man weighing 90 kg on the ground.When he is lying flat. The area of his body is contact with the ground is 0.9 m^2 .

The pressure exerted by weight of a cubical block of side 3cm on the surface is 5 Pa. Calculate the weight (or force) of the block.

The weight of a rider, driving scooter is assumed to be evenly distributed on both the tyres.The area of contact of each type with the ground is 10cm^(2) . If the pressure inside the tyres is 3 bar, find the mass of the rider (g=10ms^(-2))
