A projectile is an object projected into air with a velocity `V` so that it is moving under the influence of gravity.
a)What is the shape of the path of projectile?
b)As a projectile moves in its path,is there any point along the path where the velocity and acceleration vectors are perpendicular to each other.
c)If E is energy with a projectile is projected,
(i)What is the kinetic energy at the highest point.
(ii)What is `P.E` at highest point?
