Question

A boy of mass 62 kg is standing on skies kept on snow. Mass of each ski is 1 kg and its base area is 800 cm2. What pressure will be exerted on the snow?[take g = 10 m/s2]

Answer 1

Explanation:

Total mass= 62+1+1=64 kg

g=10ms-2

F=ma

F=64×10=640 N

Area=800cm2= 0.08m2

so, P=F/A

= 640÷0.08=8000 Pa
