The whole question is talking about the amplitude of a wave 
that's transverse and wiggling vertically.
Equilibrium to the crest . . . that's the amplitude.
Crest to trough . . . that's double the amplitude.
Trough to trough . . . How did that get in here ?  Yes, that's 
                               the wavelength, but it has nothing to do
                               with vertical displacement. 
Frequency . . . that's how many complete waves pass a mark 
                       on the ground every second.  Doesn't belong here.
Notice that this has to be a transverse wave.  If it's a longitudinal wave,
like sound or a slinky, then it may not have any displacement at all
across the direction it's moving. 
It also has to be a vertically 'polarized' wave.  If it's wiggling across 
the direction it's traveling BUT it's wiggling side-to-side, then it has 
no vertical displacement.  It still has an amplitude, but the amplitude 
is all horizontal.
        
             
        
        
        
They expend more oxygen. Littler endotherms lose warmth to the earth proportionately speedier than huge endotherms: less warm mass, protecting layers in littler creatures are less successful by dint of being more slender, and more prominent surface region to volume proportion implies snappier radiation of warmth

Answer:
The average force on ball by the golf club is 340 N.
Explanation:
Given that,
Mass of the golf ball, m = 0.03 kg
Initial speed of the ball, u = 0
Final speed of the ball, v = 34 m/s
Time of contact, 
We need to find the average force on ball by the golf club. We know that the rate of change of momentum is equal to the net external force applied such that :

So, the average force on ball by the golf club is 340 N.
 
        
             
        
        
        
2.5m/s
Explanation:
Given parameters: 
Initial velocity = 0m/s
Acceleration = 0.5m/s²
time of travel = 5s
Solution: 
Final velocity = ? 
Solution: 
 Acceleration can be defined as the change in velocity with time: 
           Acceleration = 
   From the equation above, the unknown is final velocity: 
 Final velocity - initial velocity = Acceleration x time
  since initial velocity = 0
    Final velocity = 0.5 x 5 = 2.5m/s
