A body is projected into air at an angle `theta` with the horizontal.
a)What is the trajectory followed by this projectile?
(i) Ellipse,(ii)Parabola,(iii)Straight line,(iv)Circle.
b)Give a mathematical proof for your answer.
c)Trajectory of a body in a projectile motion is given by `y=x-(x^2/80)`.
`x` and `y` are in meters.Find maximum height of this projectile.

A body is projected with a velocity v in a direction making an angle theta with the horizontal. a)Derive the mathematical equation of the path followed. b)Draw the velocity - time graphs for the horizontal and vertical components of velocity of the projectile. c)Obtain an expression for the time of flight of the projectile.

Projectile is a particle which is projected into the air with an initial velocity against gravity. a)What is the angle of projection for maximum horizontal range? b)Draw the trajectory of a projectile. c)Obtain the expression for time of flight.

"An object that is in flight after being thrown or projected is called a projectile" a)Which of the following remains constant throughout the motion of the projectile? (i)vertical component of velocity. (ii)Horizontal component of velocity. b)Derive an expression for a maximum range of a projectile. c)Show that range of projection of a projectile for two angels of a projection alpha and beta is same where alpha + beta =90° .
