Assertion : A rocket in flight is an illustration of projectile Reason : Because roket is not projected with some initial veloctity .

Rocket in flight is not an illustration of projectle . Rocket takes flight due to combustion of fuet and does not move undr the graveity effect alone.

Two projectiles are projected from the same point different velocities and different angles of projection .If the maximum height attained by both the projectiles is same, show that sum of the times taken by each to reach the highest point is equal to the total time of flight of either of the projectiles .

Statement-1: During flight under action of gravity, the change in velocity of a projectile in same time interval is same. (Neglect air friction) Statement-2: Neglecting air friction, the acceleration of projectile is constant during flight.

A projectile can have the same range R for two angle of projection . If t-1 and t_2 be the terms of flight in the two cased then the initial velocity of projectile is?

Find time of flight and range of the projectile along the inclined plane as shown in figure. (g = 10 m//s^2)

Find time of flight and range of the projectile along the inclined plane as shown in figure. (g = 10 m//s^2)

Find time of flight and range of the projectile along the inclined plane as shown in figure. (g = 10 m//s^2)

Prove that the time of flight T and the horizontal range R of a projectile are connected by the equation: gT^2 =2 R tan theta , where theta is the angle of projection.

In the following questions, a statement of assertion is followed by a statement of reason (R). Mark the correct choice as : Assertion. For a projectile the time of flight of a body becomes n times the original value if its speed is made n times. Reason. For a projectile, this is due to the range of the projectile which becomes n times.
