A projectile fired with initial velocity `u` at some angle `theta` has a range `R`. If the initial velocity be doubled at the same angle of projection, then the range will be
Assertion: A particle is projected with speed `u` at an angle `theta` with the horizontal. At any time during motion, speed of particle is `v` at angle `alpha` with the vertical, then `v sin alpha` is always constant throughout the motion. Reason: In case of projectile motion, magnitude of radial acceleration at topmost point is
The ceiling of a hall is `30 m` high. A ball is thrown with `60 ms^(-1)` at an angle `theta`, so that it could reach the ceiling of the hall and come back to the ground. The angle of projection `theta` that the ball was projected is given
Assertion: For projection angle `tan^(-1) (4)`, the horizontal and maximum height of a projectile are equal. Reason: The maximum range of projectile is directly proportional to square of velocity and inversely proportional to acceleration due to
Projectile motion is a form of motion in which an object or particle is thrown with some initial velocity near the earth’s surface and it moves along a curved path under the action of gravity alone. The path followed by a projectile is called its trajectory, which is shown below. When a projectile is projected obliquely, then its trajectory is as shown in the figure below Here velocity `u` is resolved into two components, we get (a) `u cos theta` along `OX` and (b) `u sin theta` along `OY`.The example of such type of motion
