Speed of the motorcycle,
Distance traveled by the motorcycle,
We know that,
∴
Plug in 20 km for and 45 km/h for . Solve for time.

Answer:
<em>The frequency changes by a factor of 0.27.</em>
<em></em>
Explanation:
The frequency of an object with mass m attached to a spring is given as
=
where is the frequency
k is the spring constant of the spring
m is the mass of the substance on the spring.
If the mass of the system is increased by 14 means the new frequency becomes
=
simplifying, we have
=
=
if we divide this final frequency by the original frequency, we'll have
==> ÷
==> x
==> 1/3.742 = <em>0.27</em>
