A stone projected with a velocity u at an angle $\theta$ with the horizontal reaches maximum height $H_1$. When it is projected with velocity u at an angle $\left( {\frac{\pi }{2} - \theta } \right)$ with the horizontal, it reaches maximum height $H_2$. The relation between the horizontal range R of the projectile, $H_1$ and $H_2$ 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 $h = Ax – Bx^2$ where h is height, $x$ is horizontal distance, A and B are constants. The ratio A : B is ($g = 10 m/s^2$)
Which of the following sets of factors will affect the horizontal distance covered by an athlete in a long–jump event
A ball thrown by one player reaches the other in 2 sec. the maximum height attained by the ball above the point of projection will be about
In a projectile motion, velocity at maximum height is
If two bodies are projected at 30o and 60o respectively, with the same velocity, then
A body is thrown with a velocity of 9.8 m/s making an angle of 30o with the horizontal. It will hit the ground after a time
The equation of motion of a projectile are given by $x = 36 t$ metre and $2y = 96 t – 9.8 t^2$ metre. The angle of projection is
For a given velocity, a projectile has the same range R for two angles of projection if $t_1$ and $t_2$ are the times of flight in the two cases then
A body of mass m is thrown upwards at an angle ? with the horizontal with velocity v. While rising up the velocity of the mass after t seconds will be
