Find the magnitude and direction to the velocity of an object at any instant during the oblique projection of projectile.

Find the relation between velocity of rod and that of wedge at any instant .

Assertion: In projectile motion, the acceleration is constant in both magnitude and direction but the velocity changes in both magnitude and direction. Reason: When a force or accelration is acting in an oblique direction to the direction of velocity then both magnitude and direction of the velocity may be changed.

Give one example when the velocity of an object changes at a constant rate both in magnitude and direction.

The range of a projectile is R when the angle of projection is 40^(@) . For the same velocity of projection and range, the other possible angle of projection is

A particle is projected from origin in xy-plane and its equation ,of trajectory is given by y = ax - bx^(2) . The only acceleration ,in the motion is' f' which is constant and in -ve direction of, y-axis. (a) Find the velocity of projection and the angle of projection. (b) Point of projection is considered as origin and x-axis along the horizontal ground. Find the horizontal range: and maximum height of projectile. Projectile completes its flight in horizonal plane of projection.

The angle between the direction of velocity and acceleration at the highest point of a projectile path is______ .

A : The direction of velocity of an object can be reversed with constant acceleration. R : A ball projected upward reverse its direction under the effect of gravity.

Say Yes or No: a. Can an object moving towards north have acceleration towards south? b. Can an object reverse the direction of its motion even thouth it has reverse the direcleration? C. Can an object reverse the derction of its acceleration even though it continues to move in the same dirction? d. Average speed is the magnitude of average velocity e. At any instant of time. the directions of change in velocity and acceleration are differnt.

Name the quantity which remains unchanged during the flight of an oblique projectile.

A projectile shot at an angle of 45^(0) above "the horizontal strikes a building 30m away at a point 15m above the point of projection.The magnitude and direction of velocity of projectile when it strikes the building?
