A littler girl is playing with her foot jump. The ball in her foot jump is in uniform circular motion and makes 20 revolutions in 4 seconds.
Added by Lvely J.
Step 1
Frequency = (Number of revolutions) / (Time in seconds) Frequency = 20 revolutions / 4 seconds = 5 revolutions/second Now, we need to find the angular velocity, which is the rate of change of the angle in radians per second. Show more…

A gymnast does cartwheels along the floor and then launches herself into the air and executes several flips in a tuck while she is airborne. If her moment of inertia when executing the cartwheels is $13.5 \mathrm{kg} \cdot \mathrm{m}^{2}$ and her spin rate is 0.5 rev/s, how many revolutions does she do in the air if her moment of inertia in the tuck is $3.4 \mathrm{kg} \cdot \mathrm{m}^{2}$ and she has $2.0 \mathrm{s}$ to do the flips in the air?
A girl rolls a ball up an incline and allows it to return to her. For the angle $\theta$ and ball involved, the acceleration of the ball along the incline is constant at $0.25 g$, directed down the incline. If the ball is released with a speed of $4 \mathrm{m} / \mathrm{s}$, determine the distance $s$ it moves up the incline before reversing its direction and the total time $t$ required for the ball to return to the child's hand.
A game played by many children involves placing a cuff around one ankle that has a ball attached to it by a string 2 feet long. The ball is spun around the child's leg while he or she jumps over the rope with the other foot. Suppose the ball is making one revolution per second. Calculate the linear speed of the ball in feet per second.
