Answer:
73500 Pa or 73.5 KPa
Explanation:
Mass of elephant (m) = 500 kg
acceleration due to gravity (g)= 9.8 m/s^2
weight of elephant = mg
= 500 × 9.8
= 4900 N
force by bridge on elephant (F)= weight of elephant = 490 N
Area of bridge (A)= 5 × 3 = 15 m^2
Pressure =FA = 4900 × 15
= 73500 Pa
= 73.5 KPa
