Answer: acceleration is 0.5 m/s^2
Explanation: From the question, we are given the following parameters
Time t = 20s
Initial velocity U = 0
Final velocity V = 10 m/s
Using first equation of motion,
V = U + at
Where a = acceleration
Substitute all the parameters into the formula to get acceleration a
10 = 0 + 20a
10 = 20a
Make a the subject of formula
a = 10/20 = 0.5 m/s^2
The acceleration is 0.5 m/s^2
Answer:
a. yes
Explanation:
The initial speed of the circular saw is:
Deceleration rate needed to stop the circular saw is:
The number of turns associated with such deceleration rate is:
Since the measured number of revolutions is lesser than calculated number of revolution, the circular saw meets specifications.
Answer:
The wavelength is
The frequency is
Explanation:
From the question we are told that
The distance between two successive crest is 0.80 m
The velocity is v = 2.6 m/s
Generally wavelength is the distance between two successive crest
So
Now the frequency is mathematically represented as
