East component: 3.9 m/s
South component: 1.8 m/s
Explanation:
We have to resolve the velocity vector along the east and south axis.
Taking east as positive x-direction and south as positive y-direction, the components of the velocity are given by:
where
v = 4.3 m/s is the magnitude of the velocity
is the angle between the direction of the velocity and of the x-axis
Substituting into the equations, we find:
East component:
South component:

Friction, gravity, normal force, drag force, tension force and human force are the forces that occurs on free body.
<h3>What are the forces in a free body diagram?</h3>
There are large number of external forces acting on an object such as friction, gravity, normal force, drag force, tension force and human force due to pushing or pulling. These forces can cause the motion of the free body which is present at rest form or can stop a body which is moving. A free-body diagram is a useful means of describing and analyzing all the forces that act on a body to determine equilibrium.
So we can conclude that friction, gravity, normal force, drag force, tension force and human force are the forces that occurs on free body.

Given :
Initial velocity, u = 12.5 m/s.
Height of camera, h = 64.3 m.
Acceleration due to gravity, g = 9.8 m/s².
To Find :
How long does it take the camera to reach the ground.
Solution :
By equation of motion :
Putting all given values, we get :
t = 2.56 and t = −5.116.
Since, time cannot be negative.
t = 2.56 s.
Therefore, time taken is 2.56 s.
Hence, this is the required solution.
Answer:
As a freely falling object picks up downward speed. What happens to the power supplied by the gravitational force? Does it increase, decrease or stay the same? The power will increase because (Power=work/time; work=f(d); and F x d/t; FV).
