List of top Physics Questions on Motion in a plane asked in JCECE

The motor of an engine is rotating about its axis with an angular velocity of 100 rev/m. If conies to rest in 15s, after being switched off. Assuming constant angular deceleration. What are the numbers of revolutions made by it before coming to rest?

At what angle must the two forces (x + y) and (x - y) act so that the resultant may be $\sqrt{x^2 + y^2}$ ?

The work done by the centripetal force F when the body completes one rotation around the circle of radius R is:

A rifle shoots a bullet with a muzzle velocity of $ 500\,m{{s}^{-1}} $ at a small target 50 m away. To hit the target the rifle must be aimed: (Take $ g=10\,m{{s}^{-2}} $ )

Two vectors have magnitudes 3 and 5. If angle between them is 60$^{\circ}$, then the dot product of two vectors will be
