If he were to jump to 128,100 he would’ve had jump from the stratosphere
The acceleration of the given wave is 2.5m/s^2
<h3>Wave property</h3>
The standard wave function is expressed according to the equation
y = Asin(2πft+2πx/λ)
where
λ is the wave length
Given the equation below
y = 0.120 sin((π/8)x + 4πt)
Compare both equation to have:
(π/8)x = 2πx/λ
8 = 2/λ
λ = 2/8
λ = 1/4
λ = 0.25m
For the frequency
Compare both equation to have:
4πt = 2πft
4 = 2f
4/2 = 2f/2
f = 2 Hz
Speed = fλ
speed = 2(0.25)
speed = 0.5m/s
Determine the acceleration
acceleration = change in velocity/time
acceleration = 0.5/ 0.200
acceleration = 2.5m/s^2
Hence the acceleration of the given wave is2.5m/s^2

Friction is caused by two solids rubbing together quickly.
The first two choices are both false, but the <em>second one</em> is the falser one.
All electricity sources do <em>not</em> have the same voltage. The outlet in your bedroom wall supplies 120 volts, but the USB port on your laptop only supplies 5 volts, and the battery in your cellphone only supplies 3.7 volts.
