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:
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s
Explanation:
We have equation of motion
S = ut + 0.5at²
Here u = 0, a = g and t = 9.3 s
We have equation of motion v = u +at
Substituting
v = u +at
v = 0 + 9.8 x 9.3 = 91.14 m/s
To the nearest integer, the penny's speed in m/s be right as it reaches the ground if it was dropped from rest = 91 m/s

A 1-newton mass on earth would be 1000 newtons on star Z.
Funny enough, stars like this exist~! They're called "Neutron Stars."
