Answer:
Farm = 98.1 [N]
Explanation:
To solve this problem we must draw the respective free body diagram, with the forces acting on the monkey. An analysis of the sums on the y-axis must be performed, in this axis the weight is acting down and the forces of both arms pulling up.
Weight is defined as the product of mass by gravitational acceleration.
W = m*g
where:
m = mass = 20 [kg]
g = gravity acceleration = 9.81 [m/s²]
W = 196.2 [N] (units of Newtons)
As this force points down, the force of both arms must go up, therefore each arm exerts a force of:
Farm = 196.2 / 2
Farm = 98.1 [N]

Answer:
Approximately , assuming that the rocket had no propulsion onboard, and that air resistance on the rocket is negligible.
Explanation:
Initial velocity of this rocket: .
When the rocket is at its maximum height, the velocity of the rocket would be equal to . That is:
.
The acceleration of the rocket (because of gravity) is constantly downwards, with a value of .
Let denote the distance that the rocket travelled from the launch site to the place where it attained maximum height. The following equation would relate
to
,
, and
:
.
Apply this equation to find the value of :
.
In other words, the maximum height that this rocket attained would be .
Again, assume that the air resistance on this rocket is negligible. The rocket would return to the ground along the same path, and would cover a total distance of .
