A 60kg performer balanceson cane the end of the cane in contact with the floor has an area of 0.92 cm² find the pressure exerted by the cane on the floor (neglect the weight of a cane)
We can use the formula:
pressure = force / area
The force exerted by the performer on the floor is equal to their weight, which we can calculate using:
weight = mass x gravity
where gravity is approximately 9.81 m/s².
weight = 60 kg x 9.81 m/s² = 588.6 N
Now we can plug in the values:
pressure = 588.6 N / 0.92 cm²
We need to convert cm² to m²:
1 cm² = 0.0001 m²
0.92 cm² = 0.000092 m²
pressure = 588.6 N / 0.000092 m²
pressure = 6,396,521 Pa
So the pressure exerted by the cane on the floor is approximately 6.4 MN/m² (megapascals per square meter).
