Tennis string tension-does it matter?
I just ordered a Prince O3 Silver Oversize racquet from www.dickssportinggoods.com yesteray. I found from the confirmation email that they made a mistake on the string tension. I asked for 50 lbs and they ordered 51 lbs. The string ordered was Wilson NXT tour 16 g. Can someone tell me if it matters. I called the custom service and was told that it could not be changed even it was their fault. I also found that this store has nothing to do with the Dick's Sport store. The web company just bought the name ot use it. Anyone knows if this is legal? Thanksl.
ok the people at the top are mistaken....
the tighter the strings the more control u get
the looser the strings the more power u get
1lb of tension wont make a great difference in the play and feel of the racquet
using the name of the store would be perfectly legal as long as the website bought the rights to it..
gdluck with the new racquet

physics Q --- finding kinetic energy?
It is not uncommon during the service of a professional tennis player for the racquet to exert an average force of 150.0 N on the ball. If the ball has a mass of 0.060kg and is in contact with the strings of the racquet for 0.030s, what is the kinetic energy of the ball as it leaves the racquet? Assume the ball starts from rest.
From
Ft=mv
(Force Fxtime of action t)=mass mxchange in speed v.
you obtain
v=Ft/m
speed of ball when it leaves the racquet.
Kinetic energy
T=mvv/2=m(Ft/m)^2/2=FxFxtxt/2m
Introduce the corresponding values in order to obtain the kinetic energy in joule.
