An object projected into air with a velocity is called a projectile.
a)What will be the range when the angle of projections are zero degrees and ninety degrees?
b)Show that for a projectile,the upward time of flight is equal to the downward time of flight.
c)At what angles will a projectile have the same range for a velocity?

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.

What is the angle between directions of velocity and acceleration at the highest point of trajectory of projectile?

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?

"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° .
