$A$ particle moves in a circle of radius $25\, cm$ at two revolutions per second. The acceleration of the particle in $m/s^2$ is

An athlete completes one round of a circular track of radius $R$ in $40 \,s$. What will be his displacement at the end of $2 \,min \,20 \,s$?

$A$ particle is moving on a circular path with a constant speed $v$. Its change of velocity as it moves from $A$ to $B$ in the figure is

$A$ body moves along a circular path of radius $15 \ cm$. It starts from a point on the circular path and reaches the end of the diameter in $3 \ s$. The angular speed of the body in $rad/s$ is

The ratio of the angular speed of the hour hand of a clock to the angular speed of the minute hand is .......

$A$ particle is moving in a circle with uniform speed. It has constant
