Question

Charity fundraiser fits 12 students into a small car if the combined rate of the car and students is 1600 kg and the combined area of the wheels touching the ground is 0.08 m square what is the pressure placed on the ground by the car and the students

Answer 1

Formula of pressure is Force/area.

Weight(Force)= 1600N
Area =0.08 sq. m

Multiply numerator and denominator by 100(depends upon no. of decimals) to make denominator without decimal.

Pressure= force/area
=160000/8
Pressure=20000 Pa

Hence, pressure = 20000 Pa
