Answer: 75.02 m
Explanation:
u = 0 ( starts from rest )
v = 50 m/s
t = 3 s
( i ) a = v - u / t
= 50 - 0 /3
= 16.67
( ii ) s = ut + 1/2 at²
= 0 × 3 + 1/2 × 16.67 × 3 × 3
= <u>75.02 m</u>

Answer:
The planes’ acceleration from A to B is 500m/s^2
Explanation:
Given that the initial velocity u is 8000m/s
and also given the final velocity v=10,000 m/s
the time taken to move from A to B = 40 second
The acceleration is defined as the rate of change of velocity with time
we know that the expression for acceleration is given as
a=(v-u)/t
substituting our given data into the expression for a we have
a=(10000-8000)/40
a=2000/40
a=500m/s^2
The planes’ acceleration from A to B is 500m/s^2
Answer:
12 m
Explanation:
The object is in uniformly accelerated motion, so the distance covered can be found using the following suvat equation:
![s=ut+\frac{1}{2}at^2](https://tex.z-dn.net/?f=s%3Dut%2B%5Cfrac%7B1%7D%7B2%7Dat%5E2)
where
s is the distance
u is the initial velocity
t is the time
a is the acceleration
For this problem,
![g=24 m/s^2](https://tex.z-dn.net/?f=g%3D24%20m%2Fs%5E2)
and
u = 0, since we are considering the first second of motion
So, substituting t = 1 s, we find
![s=0+\frac{1}{2}(24)(1)^2=12 m](https://tex.z-dn.net/?f=s%3D0%2B%5Cfrac%7B1%7D%7B2%7D%2824%29%281%29%5E2%3D12%20m)
The answer is c .Frequency
Answer:
the law of motion
Explanation:
because the wheels are moving it means motion i am not sure which number law it is but I believe that it is 2nd but u should look it up to be safe
