medium

particle is moving in a circular path. The acceleration and momentum of the particle at a certain moment are $\vec a\, = \,(4\hat i + 3\hat j)\,\,m/{s^2}$ and $\vec P\, = \,(8\hat i\, - \,6\hat j)\,kg\, - \,m/s$ . The motion of the particle is

AUniform circular motion

Baccelerated circular motion

Cdecelerated circular motion

DWe cannot say anything with $\vec a$ and $\vec p$ only

Solution

Angle between acceleration and momentum is less than $90^o$. So acceleration has two component one is $ \bot $ ar to momentum (centripetal) and another is parallel to momentum (tangential) which increases speed.

A particle moves along a circle of radius $\left( {\frac{{20}}{\pi }} \right)\,m$ with constant tangential acceleration. If the velocity of the particle is $80 \,m/s$ at the end of the second revolution after motion has begin, the tangential acceleration is

A car is moving on a circular path of radius $600\,m$ such that the magnitudes of the tangential acceleration and centripetal acceleration are equal. The time taken by the car to complete first quarter of revolution, if it is moving with an initial speed of $54\,km / hr$ is $t \left(1- e ^{-\pi / 2}\right)\,s$. The value of $t$ is $………….$.
