Question

A skateboarder lands on all four wheels after riding a railing. The skateboarder exerts 3525 kPa of pressure on the ground, and the area on the bottom of a single wheel is 0.0001 m2. Determine the mass of the skateboarder in kg.
(1 kPa = 1000 Pa) assume Gravity g=10 N/kg
weight (W)=mass (m) x gravity(g)
Pls help need it right now

Answer 1

Answer:

P = F/Aarea of four wheel is = 0.0001*4 = 0.0004P = 900/0.0004 = 2250000P = 2.25*10^5 N/m^2
