A projectile is thrown with velocity u making an angle θ with the horizontal. Its time of flight on the horizontal ground is 4 second. The projectile is moving at angle of 45^∘ with the horizontal just one second after the projection. Hence the angle θ is (take g=10m/s^2) A particle A is projected vertically [...]

A body is projected at an angle of 45^∘ with horizontal from a point on ground at distance 6m from the foot of a vertical pole. It just crosses the top of the pole and falls on ground on the other side at a distance of 3 m from the foot of the pole. The [...]

The direction of projection of particle is shown in the figure for an observer on trolley. An observer on the ground sees the ball rising vertically. The maximum height reached by the ball as seen from the trolley is A particle A is projected vertically upwards. Another particle B is projected at an angle of [...]

Ratio of minimum kinetic energies of two projectiles of same mass is 4:1. The ratio of the maximum height attained by them is also 4:1 . The ratio of their ranges would be Ratio of minimum kinetic energies of two projectiles of same mass is 4:1. The ratio of the maximum height attained by them [...]

A particle A is projected vertically upwards. Another particle B is projected at an angle of 45^∘. Both reach the same height. The ratio of the initial kinetic energy of A to that of B is: A particle A is projected vertically upwards. Another particle B is projected at an angle of 45^∘. Both reach [...]

A particle of mass m is projected from the ground with initial linear momentum p (magnitude) such that to have maximum possible range, its minimum kinetic energy will be A particle of mass m is projected from the ground with initial linear momentum p (magnitude) such that to have maximum possible range its minimum kinetic [...]

A particle is projected from the ground with an initial velocity of 20m/s at an angle of 30∘ with horizontal. The magnitude of change in velocity in a time interval from t=0 to t=0.5s (g=10m/s^2) A particle is projected from the ground with an initial velocity of 20m/s at an angle of 30∘ with horizontal.

Velocity of a particle varies with time as v=atiˆ+2ht2jˆ. If the particle starts from point (0,c), the trajectory of the particle is C the trajectory of the particle is Velocity of a particle varies with time as v=atiˆ+2ht2jˆ. If the particle starts from point (0 October 18, 2020 Category: Arihant Physics by D.C Pandey , [...]

A car breaks a traffic signal with a speed of 40m/s. After 2s, a policeman starts following him with a constant acceleration of 12.5m/s^2. Taking the position of signal to be origin, correct position time graph would be A car breaks a traffic signal with a speed of 40m/s. After 2s a policeman starts following [...]

An airplane flies northward from town A and B and then back again. There is a steady wind blowing towards the north so that for the first state of the trip, the airplane is flying in the same direction as the wind and for the return trip of the journey, the airplane is flying opposite [...]
