Aperson who weighs 625 n is riding a 98-n mountain bike. suppose that the entire weight of the rider and bike is supported equally by the two tires. if the pressure in each tire is 7.60 x 10^5 pa, what is the area of contact between each tire and the ground?

A = 4.76 x 10⁻⁴ m²

Explanation:

given,                                  

weight of the person = 625 N

weight of the bike = 98 N        

Pressure on each Tyre = 7.60 x 10⁵ Pa

Area of contact on each Tyre = ?          

total weight of the system = 625 + 98

                                             = 723 N

Let F be the force on both the Tyre

F + F = W                                    

2 F  = 723                                    

F = 361.5 N                                

F = P A                                            

A = 4.76 x 10⁻⁴ m²
