A person has a mass of 50.0 kg. What is the pressure they exert on the blades of their ice skates if each skate blade is 15.0 cm long and 5.00 mm wide?
To calculate the pressure exerted by a person on the blades of their ice skates, we need to know the force exerted by the person and the area over which the force is distributed.
First, let's calculate the area of each skate blade:
Area = length × width
Area = 0.15 m × 0.005 m = 0.00075 m²
Next, let's calculate the force exerted by the person:
Force = mass × acceleration due to gravity
Force = 50.0 kg × 9.8 m/s² = 490 N
Finally, we can calculate the pressure using the formula:
Pressure = Force / Area
Pressure = 490 N / 0.00075 m² = 653,333.33 Pa
Therefore, the pressure exerted by the person on the blades of their ice skates is approximately 653,333.33 Pascal (Pa).
