If time of flight of a projectile is 10 sec. range is 500 m. The maximum height attained by its will be

A bullet is fired from a cannon with velocity 500 m/s. If the angle of projection is 15^o and g = 10 m/s². Then the range is

A ball thrown by a boy is caught by another after 2 sec same distance away in the same level. If the angle of projection is 30^o, the velocity of projection is

A ball is thrown upwards at an angle of 60^o to the horizontal. it falls on the ground at a distance of 90 m. If the ball is thrown with the same initial velocity at an angle 30^o, it will fall on the ground at a distance of

Four bodies P, Q, R and S are projected with equal velocities angles of projection 15^o, 30^o, 45^o and 60^o with the horizontal respectively. The body having shortest range is

An object is projected with a velocity of 20 m/s making an angle of 45^o with horizontal. The equation for the trajectory is h = Ax – Bx² where h is height, x is horizontal distance, A and are constants. The ratio A : B is (g = 10 ms^–2)

Which of the following sets of factors will affect the horizontal distance covered by an athlete in a long-jump event?

In a projectile motion, velocity at maximum height is

A body of mass m is thrown upwards at angle θ with the horizontal with velocity v. While rising up the velocity of the mass after t seconds will be

A cricketer can throw a ball to a maximum horizontal distance of 100 m. With the same effort, he throws the ball vertically upwards. The maximum height attained by the ball is
