Force is measured according to which law of motion

Range of a projectile on a horizontal plane is same for the following pair of angles:

A body moves from point P (3, 4) to Q (5, 7). Its displacement vector would be

How is the motion of a body affected by balanced and unbalanced forces acting on it?

A force of 10 N acts on a body of mass 1 kg for 5 sec to a distance of 10 m. The rate of change of momentum is:

The displacement after half a circle of radius “r” would be

A baseball is thrown vertically into the air. The acceleration of the ball at its highest point is

At what angle of projection, horizontal and vertical component of velocities have same values?

Accelerating frame of reference which has constant acceleration is

A body of mass M collides against a wall with a velocity v and retraces its path with the same speed. The change in momentum is (take the initial direction of the velocity as positive)
