a 40 kg student is riding a bicycle to school. the bicycle has a mass of 12 kg. the area that each tire makes contact with the road can be approximated by a rectangle of dimensions 6 cm x 4 cm. what is the pressure that each tire exerts on the road? give your answer in kPa to the nearest tens place
P=(m₁+m₂)g/A=(40+12) •9.8/2(6•4)•10⁻⁴=106167 Pa= 106.167 kPa
