An auto race takes place on a circular track. A car completes one lap in a time of 18.0 s, with an average tangential speed of 4
eduard

Answer:

(A) 0.3488 rad/sec

(B) 124.246 m                

Explanation:

We have given car completes one revolution in 18 sec'

So time period T= 18 sec

Tangential speed v = 43.4 m/sec

(A) Angular velocity is given by \omega =\frac{2\pi }{T}=\frac{2\times 3.14}{18}=0.3488rad/sec

(B) Tangential velocity is given v = 43.4 m /sec

We know that v=\omega r

r=\frac{v}{\omega }=\frac{43.4}{0.3488}=124.426m

The same bungee jumper from the previous question is now safely back on the ground, but hungry. He eats an apple before going fo
kramer

D. The energy transfer he is experiencing is Chemical to kinetic.

<h3>Conservation of energy</h3>

The principle of conservation of energy states that energy can neither be created nor destroyed but can be converted from one form to another.

The apple eaten by the bungee jumper will provide chemical energy which will be converted into kinetic energy of the jumper once he is in motion.

Thus, the energy transfer he is experiencing is Chemical to kinetic.
