Question

A Projectile is fired upward at an angle with horizontal with velocity u.
Show its trajectory is parabola. Obtain expression for

i) Maximum height
ii) Time of flight
iii) Range


​

Answer 1

Answer:

Two particles projected from the same point with same speed u at angles of projection α and β strike the horizontal ground at the same point. If h

1

and h

2

are the maximum heights attained by the projectile, R is the range for both t

1

and t

2

are their times of flights, respectively, then
