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

all u need to do is use the equation -b/2a
use the equation for the height of an object which is h(t)= -g(t)+ V,(t) + h,
sorry dont know how to type equations so
`=squared h=height
,=initial t=time
V=velocity g=gravitational constant
uh also use the equation for a parabola
x=ax` +bx +c
so the ten is b and -9.8 is a
so the answer is -10/(2)(-9.8)
i probably could have explained this a lot easier ... oh well
