Answer:
Yes we can find the initial velocity of car without finding acceleration.
u = 10 m/s.
Explanation:
Given that
s=20 m
Car takes 4 s to come in rest.
We know that when acceleration is constant then we can apply motion equation
----------1
------2
From equation 1 and 2
So we can say that
Given that the velocity of car at final condition will be zero (v=0)
From the above equation we can find the initial velocity of car without finding the acceleration
u = 10 m/s
The frequency of the radio wave is:
The wavelength of an electromagnetic wave is related to its frequency by the relationship
where c is the speed of light and f the frequency. Plugging numbers into the equation, we find
and this is the wavelength of the radio waves in the problem.
