The answer you are looking for is 22 mph.
Solution:
s=speed
d=distance
t=time
Setting up the formula for the speed of an object with distance and time:
s=d/t
Substituting the given values,
s=88 miles/4 hours
So, therefore, the final answer is 22 mph.
I hope this helped answer your question for you. Good day to you.
Answer:
Acceleration and the distance traveled are 0.9 m/s² and 4.05 m
Explanation:
Given that,
Initail speed, u = 0
Final speed, v = 2.7 m/s
Time, t = 3 s
To find,
The acceleration and distance traveled.
Solution,
Acceleration is change in speed per unit time

Let s is the distance,

So, acceleration and the distance traveled are 0.9 m/s² and 4.05 m

Answer:
Heat Input = Work Output (at 100% efficiency)
ΔQ = ΔW
(you cannot get something for nothing)
Since the two trains are passing in opposite
directions, so this means that their relative velocities will be the sum of the
two trains that is:
<span>
relative velocity = (13 + 28) = 41m/s</span>
<span>
a. The passengers aboard on train B will see that train A is
moving at 41m/sec due east</span>
<span>b. The passengers aboard on train A will see that
train B is moving at 41m/sec due west</span>
