Rise of an object-Physics (Posted on 2003-04-01)

If a 7kg object is thrown straight upwards at a speed of 10m/s(meters per second)

To what height will it rise? note: gravitational constant = -9.8m/s

m=7kg ; v=10m/s ; g=9.8m/s²
Ep=m*g*h ; Ek=(m*v²)/2
Ep=Ek
7kg*9.8m/s²*h=(7kg*10m/s²)/2
68.6h=350
h=5.1
