A mimibus drives with a constant speed of 39 km/h. how far can it travel in 1.94 hours?
1 answer:
Answer:
<em>The minibus traveled 75.66 km</em>
Explanation:
<u>Motion with Constant Speed </u>
An object is said to travel at constant speed if the ratio of the distance traveled by the time taken is constant.
The formula to calculate the speed is:
Where
v = Speed of the object
d = Distance traveled
t = Time taken to travel d.
From the equation above, we solve for d:
d = v . t
The minibus has a constant speed of v=39 km/h and it's required to find the distance it travels in t=1.94 hours.
Calculating the distance:
d = 39 km/h * 1.94 h
d = 75.66 km
The minibus traveled 75.66 km

Answer:
a. The angular frequency is doubled.
e. The period is reduced to one-half of what it was.
Explanation:
Angular frequency is given as;
ω = 2πf
when the frequency is doubled
Thus, the angular frequency will be doubled.
Amplitude in simple harmonic motion is the maximum displacement.
Frequency is related to period in simple harmonic motion as given in the equation below;
when the frequency is doubled;
Thus, the period will be reduced to one-half of what it was.
