A girl running around a circular track of radius 200 m completes one

kondor19780726 [428]

Answer:

v = 2 m/s

Explanation:

First, we find the angular velocity of the girl by using the following formula:

$Angular\ Velocity =\omega= \frac{Angular\ Distance\ Covered}{Time\ Taken}\\\\\omega = \frac{1\ revolution}{10\ min}\frac{1\ min}{60\ s}\frac{2\pi\ rad}{1\ revolution}\\\\\omega = 0.01\ rad/s$

Now, for the average velocity of the girl we can use the following formula:

$Average\ Velocity = V = r\omega\\V = (200\ m)(0.01\ rad/s)\\$

where,

r = radius = 200 m

therefore,

A 0.954-kg toy car is powered by three D cells (4.50 V total) connected directly to a small DC motor. The car has an effective e

Natasha2012 [34]

Answer:

0.06 A

Explanation:

We have given mass =0.954 kg

velocity =1.27 m/sec

efficiency =0.361 the output kinetic energy of the motor $KE=\frac{1}{2}mv^2=\frac{1}{2}\times 0.954\times 1.27^2=0.769\ J$
