Answer:
1. F = 3400 N = 3.4 KN
2.

3. v = 14.9 m/s
Step-by-step explanation:
1.
First, we will calculate the acceleration of Pam by using the third equation of motion:

where,
a = acceleration = ?
s = distance = 27.3 m
vf = final speed = 62 m/s
vi = initial speed = 0 m/s
Therefore,

Now, we will calculate the force by using Newton's Second Law of Motion:
F = ma
F = (48.3 kg)(70.4 m/s²)
F = 3400 N = 3.4 KN
2.
Final kinetic energy is given as:


3.
According to the law of conservation of energy:

where,
v = speed at bottom = ?
g = acceleration due to gravity = 9.81 m/s²
h = height at top = 11.3 m
Therefore,

v = 14.9 m/s
