A bicycle rider travels 50.0 km in 2.5 hours. Determine the cyclists average speed.
k0ka [10]
There are several information's already given in the question. Based on those information's the answer can be easily deduced.

Distance traveled by the bicycle rider = 50 km
Time taken to travel the distance = 2.5 hours
So
In 2.5 hours the bicycle rider travels = 50 km
Then
In 1 hour the bicycle rider travels = 50/2.5
                                                     = 20 km
Then the average speed of the cyclist is 20 km per hour.

"If you double the wavelength of a wave on a particular string", what happens to the wave speed v and the frequency f ? (i) v do
nadezda [96]

Answer:

v doubles and f is unchanged

Explanation:

According to the formula v = f¶

Where v is the velocity of the wave

f is the frequency

¶ is the wavelength

Velocity is directly proportional to wavelength. Direct proportionality shows that increase in velocity will cause an increase in the wavelength and decrease in velocity will also cause a decrease in wavelength with the frequency not changing since the velocity and wavelength are both increasing and decreasing at the same rate.

According to the question, if the wavelength is doubled, the velocity (v) will also double while the frequency (f) remains unchanged.

If the thrower takes 0.90 s to complete one revolution, starting from rest, what will be the speed of the discus at release?
Marysya12 [62]
Ω₀ = the initial angular velocity (from rest)
t = 0.9 s, time for a revolution
θ = 2π rad, the angular distance traveled

Let
α =  the angular acceleration
ω =  the final angular velocity

The angular rotation obeys the equation
(1/2)*(α rad/s²)*(0.9 s)² = (2π rad)
α = 15.514 rad/s²

The final angular velocity is
ω = (15.514 rad/s²)*(0.9 s) = 13.963 rad/s

If the thrower's arm is r meters long, the tangential velocity of release will be 
v = 13.963r m/s

Answer: 13.963 rad/s
