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

Answer:
The thrust that you feel at the time of firing is one of the real-life example of the conseriation nomentum
Answer:
just-noticeable difference
Explanation:
Using principles of psychology and physics, a branch of experimental psychology called psychophysics has been created. This field is focused on the sensation, the sense and the perception of stimuli. Within this branch it has been called just-noticeable difference to the amount that must be changed of some stimulus so that this difference is noticeable, that is to say, the threshold at which the change is perceived.
Jack Nicklaus once said about golf that "hitting a perfectly straight shot with a big club is a fluke." Science of Golf (SOG): Newton’s Third Law of Motion and Momentum explains what happens when a golfer swings a golf club and applies a big force to the small golf ball. The video features amateur golfer and Stanford University student Patrick Rodgers who gives his opinion on the importance of knowing what causes power and speed in the golf swing. Jim Hubbell, research engineer at the United States Golf Association (USGA) discusses what forces are and how they work in pairs. Hubbell also defines momentum and how it is transferred to the ball.
