a)
An object of mass 2 kg is launched at an angle of
30o above the ground with an initial speed of 40 m/s.
Neglecting air resistance , calculate:
i.
the kinetic energy of the object when it is launched
from the the ground.
ii.
the maximum height attained by the object .
iii.
the speed of the object when it is 12 m above the
ground.
