What pressure is exerted on the snow by a skier weighing 78 kg, if the length of each ski is 1.95 m and the width is 8 cm.
| November 27, 2020 | education
p = mg / s
p pressure
m weight = 78kg
g free fall speed = 10m / s
s = 1.95m * 0.08m
substitute numbers in the equation
p = 78 * 10 / 1.95 * 0.08
consider
the ideal answer is 5000Pa = 5000n / m ^ 2 = 5kPa
Answer: the pressure of the skier on the snow is 5kPa = 5000Pa
