Projectile Motion Formulas - Concepts and Solved Examples
There are many types of motion around us. Projectile motion is a form of motion experienced by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible). Such an object is called a projectile and the curved path with which the projectile travels is what is termed as trajectory.
Formulae related to a projectile that is launched at an oblique angle with respect to the horizontal and whose motion is referred with respect to the horizontal are:
(v0 is the velocity of projection, θ
Question: If the horizontal range of a projectile is 4 times the maximum height attained by it, then the angle of projection is: Options: (a) 45° (b) 30° (c) 60° (d) 15° Answer: (a)
