QUESTION
Calculate the pressure exerted by a 200 N force over an area of 2 m².
QUESTION
Determine the pressure at a depth of 10 m in water (
ρ
=
1000
kg/m
3
\rho = 1000 \text{ kg/m}^3
ρ
=
1000
kg/m
3
,
g
=
9.8
m/s
2
g = 9.8 \text{ m/s}^2
g
=
9.8
m/s

ANSWER
Acceleration = 2 m/s². Using
a
=
F
m
a = \frac{F}{m}
a
=
m
F
where
F
=
20
F = 20
F
=
20
N and
m
=
10
m = 10
m
=
10
kg.
