A particle of mass m is projected with a velocity u making an angle \(\theta\) with the horizontal. The magnitude of angular momentum of the projectile about the point of projection when the particle is at its maximum height is

When a ball is thrown with a velocity of 50 ms\(^{-1}\) at an angle 30\(\Upsilon\) with the horizontal, it remains in the air for ......... s.

(Take, g = 10 ms\(^{-2}\))

A hiker stands on the edge of a cliff \(490 \mathrm{~m}\) above the ground and throws a stone horizontally with an initial speed of \(15 \mathrm{~ms}^{-1}\). The speed with which it hits the ground is

Two paper screens \(A\) and \(B\) are separated by \(150 \mathrm{~m}\). A bullet pierces \(A\) and than \(B\). The hole in \(B\) is \(15 \mathrm{~cm}\) below the hole in \(A\). If the bullet is travelling horizontally at the time of hitting \(A\), then the velocity of the bullet at \(A\) is \(\left(\mathrm{g}=10 \mathrm{~ms}^{-2}\right)\)

A boy throws a cricket ball from the boundary to the wicket keeper. If the frictional force due to air \((f_a )\) cannot be ignored, the forces acting on the ball at the position X are represented by

A force \(\mathbf{F}_1\) of magnitude 4 N acts on an object of mass 1 kg , at origin in a direction \(30^{\circ}\) above the positive \(X\)-axis. A second \(F_2\) of magnitude 4 N acts on the same object in the direction of the positive \(Y\)-axis. The magnitude of the acceleration of the object is nearly.

A car travels with a speed of \(40 \mathrm{~km} \mathrm{~h}^{-1}\). Rain drops are falling at a constant speed vertically. The traces of the rain on the side windows of the car make an angle of \(30^{\circ}\) with the vertical. The magnitude of the velocity of the rain with respect to the car is

A projectile with speed \(50 \mathrm{~ms}^{-1}\) is thrown at an angle of \(60^{\circ}\) with the horizontal. The maximum height that can be reached is (acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\))

A projectile is launched from the ground, such that it hits a target on the ground which is 90 m away. The minimum velocity of projectile to hit the target is (acceleration due to gravity \(=10 \mathrm{~ms}^{-2}\))
