Projectile motion is a form of motion in which an object or particle is thrown with some initial velocity near the earth’s surface and it moves along a curved path under the action of gravity alone. The path followed by a projectile is called its trajectory, which is shown below. When a projectile is projected obliquely, then its trajectory is as shown in the figure below
Here velocity `u` is resolved into two components, we get (a) `u cos theta` along `OX` and (b) `u sin theta` along `OY`.
The example of such type of motion is
Options:
(a) motion of car on a banked road
(b) motion of boat in sea
(c) a javelin thrown by an athlete
(d) motion of ball thrown vertically upward
