You have:
A1= 0.15 m²
A2=6.0 m²
F1=130.0 N
To solve this problem you must use the pressure formula, as below:
P1=P2
F1/A1=F2/A2
Then, you have:
m2=A2xF1/A1xg
g=9.81 m/s² (This is the acceleration of gravity)
When you substitute the values in m2=A2xF1/A1xg, you obtain:
m2=(0.60 m² x 130.0 N)/(0.15 m² x 9.81 m/s²)
The answer is:
m2=530 Kg
Answer:
the horizontal component of the force is 50 N
Explanation:
Given;
force applied by the man, F = 100 N
angle of inclination of the force, θ = 60⁰
mass of the dog, m = 20 kg
The horizontal component of the force is calculated as;

Therefore, the horizontal component of the force is 50 N
