Answer 1

Verified answer

M = 20 kg
g = 10 m/s^2
p = 40 cm
l = 20 cm
t = 50 cm
P?

penyelesaian:
1.) cari dulu F nya:
F = m × g

F = 20 × 10

F = 200 N

2.) kemudian cari A nya:
A = p × l

A = 40 × 20

A = 800 cm^2

A = 0,08 m^2

3.) masukan rumus tekanan:
P = F / A

P = 200 / 0,08

P = 2500 N/m^2
