Take the upward and to-the-right directions to be positive (so down and to-the-left are negative).
The vertical forces acting on the object cancel, 6 N - 6 N = 0.
The horizontal forces exert a net force of 20 N - 3 N = 17 N. This net force is positive, so it points to the right. So the answer is A.
C, the autonomic system :)
In the equation for the gravitational force between two objects, the distance quantity or measurement must be squared. The formula for calculation the gravitational force between two objects is F = G*m1*m2/d^2. F is the gravitational force between the two objects. G is the constant gravity, m1 is the first object's mass, m2 is the second object's mass, and d is the distance between the two objects<span>.</span>
"Life is wasted if we do not grasp the glory of the cross, cherish it for the treasure that it is, and cleave to it as the highest price of every pleasure and the deepest comfort in every pain. What was once foolishness to us—a crucified God—must become our wisdom and our power and our only boast in this world.” - John Piper
Answer:
h = 44.5 m
Explanation:
Given that,
Power of the engine, P = 5 hP = 3728.5 W
Weight of the load, W = 2000 lb = 8900 kg
We need to find how high the load be raised in 10 s.
We know that,
Power,
Where
W is work done
Also,
1 Pound = 4.45 newtons earth (N)
So, the height raised by the load is 44.5 m.
