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
(Calculations assume the presence of a vacuum)
Because a vacuum is present, the object's mass is neglected.
After the first second of travel the object has traveled 5 m
(d=(1/2)at^2). Then the object will travel for another .1 m
(because it has decreased to a speed of .2 m/s, and applying that to
d=(1/2)at^2 will yield .1 m) and then begin to fall. Thus the
object will travel to a height of 5.1 m.
