The answer is b the transition state
We have: F = m × v/t
Here, m = 8500 Kg
v = 20 m/s
t = 10 s
Substitute their values into the expression,
F = 8500 × 20/10
F = 8500 × 2
F = 17000 N
In short, final answer would be 17000 N
Hope this helps!!
I can try and help whats it about?
The tide was high because of the sun just now coming up at noon it when the sun begins to settle causing the ocean to form at low tide .
Answer:
1850 N
Explanation:
The formula for friction force between the load and plane is given as ;
F= μ*N
N = mg cos θ
To find θ, which is the angle the inclined plane makes with the ground at the height of 1.5 m
Sin θ = 1.5/4.5
Sin θ = 0.3333
Sin⁻{0.3333} = 19.50°
θ = 19.50°
Finding N , where m= 500 N , and g= 9.81
N = mg cos θ
N= 500 * 9.81 * cos 19.50°
N= 4624 N
Coefficient of kinetic friction is calculated as;
μ=F/W
μ = 200/500 = 0.4
The magnitude of kinetic friction is given as;
Fk= μ * N
Fk = 0.4 * 4624
Fk= 1850 N
