Two stones are projected with the same speed but making different angles with the horizontal. Their horizontal ranges are equal. The angle of projection of one is $\pi / 3$ and the maximum height reached by it is $102\, m$. Then the maximum height reached by the other in metre is

Two equal vectors have a resultant equal to either of them, then the angle between them will be

A body is projected at such angle that the horizontal range is three times the greatest height. The angle of projection is

The $(x, y, z)$ coordinates of two points $A$ and $B$ are given respectively as $(0, 3,-1)$ and $(-2, 6, 4)$. The displacement vector form $A$ to $B$ may be given by:

A can is moving horizontally along a straight line with constant speed $30\, m/s$. A projectile is to be fired from the moving cart in such a way that it will return to the cart after the cart has moved $80 \,m$. At what speed (relative to the can) must the projectile be fired? (Takes $ =10\,m/{{s}^{2}} $ )

A particle is moving in a circle of radius R with constant speed v. If radius is doubled, then its centripetal force to keep the same speed gets:

A bullet of mass $0.1 \,kg$ is fired with a speed of $100 \,m/s.$ The mass of gun being $50 \,kg$. Then, the velocity of recoil become:
