m=0.45 Kg
change in velocity= Vf - Vi =7-(-4)=11m/s.
Rate of change of velocity = (11/0.04) m/s2
Average force on ball = m x (11/0.04) = 123.75 newton Answer
His velocity was zero - since he's back to where he started. (Try to substitute speed where appropriate.)
It's 600.00 yens

About 30AA- 32AA, dont worry, when you hit about 12 for most girls you go up a few sizes, so you'll assets will look nice ;0!
All able-bodied Americans should represent themselves . Get involved and hit the streets! Protest in a non-violent way, but make your voice heard.
Calculate the total time, and the total distance. Divide the total distance by the total time. This will give you the average speed.
US homes use a 240 volt single phase 'Edison' system. It is a 3-wire (4 with the ground) system. Phase to phase measures 240v, while each phase to neutral measures 120v.
