Please help me with part 2. Will give brainliest
1 answer:
Hi there!
We can use the derived equation to solve:
, where:
h = height
g = acceleration due to gravity
Plug in the given values. Remember to CONVERT km to m:
32 km = 32 km * 1000 m / 1 km = 32,000 m
t = √(2(32000)/3.4) ≈ <em>137.199 sec</em>
Part 2:
Use the derived equation:
vf = √2gh
vf = √(32000)(3.4) = <em>329.848 m/s</em>

The power expended is 500 W
Explanation:
First of all, we start by calculating the work done by the man in order to ascend: this is equal to the gravitational potential energy gained by the man, which is
where
m = 50 kg is the mass of the man
is the acceleration of gravity
is the change in height
Substituting,
Now we can calculate the power expended, which is given by
where
W = 2500 J is the work done
t = 5 s is the time elapsed
Substituting, we find

The maximum speed of the object under simple harmonic motion is 0.786 m/s.
The given parameters:
- Position of the particle, y = 0.5m sin(πt/2)
y = A sin(ωt + Ф)
where;
- A is the amplitude = 0.5 m
- ω is the angular speed = π/2
The maximum speed of the object is calculated as follows;
Thus, the maximum speed of the object under simple harmonic motion is 0.786 m/s.
