An ant clings to the outside edge of the tire of an exercise bicycle. When you start pedaling, the ant's speed increases from zero to 11 m/s in 2.4 s. The wheel's rotational acceleration is 15 rad/s². What physical quantities can be determined from this information? Check all that apply. The radius of the tire. The average tangential acceleration of the tire. The distance the ant has traveled along the arc during this time interval. The rotational momentum of the ant. The angle the ant has turned during this time interval. The rotational momentum of the tire.

Step 1
4 s. We can calculate the average tangential acceleration ($a_t$) using the formula: $a_t = \frac{\Delta v}{\Delta t} = \frac{11 \, m/s - 0 \, m/s}{2.4 \, s} = \frac{11}{2.4} \, m/s^2 \approx 4.58 \, m/s^2$ Show more…

* An ant clings to the outside edge of the tire of an exercise bicycle. When you start pedaling, the ant's speed increases from zero to $10 \mathrm{m} / \mathrm{s}$ in $2.5 \mathrm{s}$. The wheel's rotational acceleration is $13 \mathrm{rad} / \mathrm{s}^{2} .$ Determine everything you can about the motion of the wheel and the ant.
