Speed of the wave will be = 129 m/s
given
mass = 60 g = 0.06 kg
length = 2 m
wave speed = v =
T = Tension of the rope = 500 N
mu = linear mass density
mu = mass / length
= 0.06 / 2 = 0.03 kg/m
v = = 129 m/s
speed of the wave will be = 129 m/s

The kinetic energy needed by the man is
Explanation:
The escape velocity (the speed needed by an object in the Earth's surface to escape the Earth's gravitational field) is given by
where
G is the gravitational constant
M is the Earth's mass
R is the radius of the Earth
For the Earth, we have
Substituting, we find the escape velocity:
Now we can find the kinetic energy that the man would need, which is given by
where
m = 65 kg is the mass of the person
is the escape velocity
Substituting,
