Answer: 4550 Joules

The formula for potential energy in gravitational field is as follows:

E_{pot} = mgh=65kg \cdot 10 \frac{N}{kg} \cdot 7m = 4550 J

A 0.200 kg block on a vertical spring with spring constant of 4.65 ✕ 103 N/m is pushed downward, compressing the spring 0.084 m.
vlada-n [284]

Answer:

PEel = PEg

PEel = .5 * k * x^2

= .5 * 4650 * .1^2

= 23.25

PEg= m * g * h

=.2 * 9.81 * h

23.25 = 1.962* h

h = 11.85

A force of 20 newtons is exerted on a chair from its right and a force of 12 newtons is applied from its left. What is the net f
jeka94
The net force is the sum of the forces acting on an object ( chair ).
F net = F 1 + F 2
F 1 = 20 N, F 2 = - 12 N
F net = 20 N + ( - 12 N ) = 8 N
The chair will tend to move to the left.

32. A forest ranger. 35 meters above the ground in a
Sphinxa [80]

Answer:

x = 102.33 m

Explanation:

Given that,

Position where a forest ranger stands is 35 m above the ground. The angle of depression to the base of the fire is 20. We need to find how far from the tower is the fire.

Let the distance is x. We can find x using trigonometry as follows :

\sin\theta=\dfrac{\text{perpendicular}}{\text{hypotenuse}}\\\\\sin(20)=\dfrac{35}{x}\\\\x=\dfrac{35}{\sin(20)}\\\\x=102.33\ m

Hence, the fire is at a distance of 102.33 m from the fire.
