AIPMT-PRELIMS Physics Motion in a Plane Class 11 Questions

The horizontal range and the maximum height of a projectile are equal. The angle of projection of the projectile is

A body is moving with velocity 30 m/s towards east. After 10 seconds its velocity becomes 40 m/s towards north. The average acceleration of the body is

A missile is fired for maximum range with an initial velocity of 20 m/s. If g = 10 m/s², the range of the missile is

For angles of projection of a projectile at angles (45°+θ) and (45°-θ), the horizontal ranges described by the projectile are in the ratio of:

The circular motion of a particle with constant speed is:

A particle (A) is dropped from a height and another particle (B) is projected in horizontal direction with speed of 5 m/s from the same height then correct statement is :-

A particle is projected making angle 45° with horizontal having kinetic energy K. The kinetic energy at highest point will be:

Two projectiles of same mass and with same velocity are thrown at an angle 60° & 30° with the horizontal, then which quantity will remain same:

The width of river is 1 km. The velocity of boat is 5 km/hr. The boat covered the width of river with shortest will possible path in 15 min. Then the velocity of river stream is :
