oblicz cisnienie jakie wywiera na podloze skrzynia o masie 50kg i polu powierzchni podstawy 0,5m kwadratowy dam naj
dane:
m = 50 kg
S = 0,5 m²
g = 10 m/s²
szukane:
p = ?
p = F/S
ale F = m*g = 50kg*10m/s² = 500 N
p = 500N/0,5m² = 1000 Pa
1 kPa = 1000 Pa
p = 1 kPa
=======
Odp. Szukane ciśnienie wynosi 1000 Pa (1 kPa).
