1 answer:
Answer:
Ideal mechanical advantage of the lever is 3.
Explanation:
Given that,
The distance between the levers input force and the fulcrum is 8 cm,
The distance between the fulcrum and the output force is 24 cm,
To find,
The ideal mechanical advantage of the lever.
Solution,
The ratio of the distance between the fulcrum and the output force to the distance between the levers input force and the fulcrum is called the ideal mechanical advantage of the lever. It is given by :
m = 3
So, the ideal mechanical advantage of the lever is 3.

Answer: Hello!
Lewis is travelling at 165 mph, which means miles per hour, this says that he does 165 miles in one hour.
We want to know how much time takes to cover 16 miles.
this can be calculated as the quotient of the distance and the velocity; this is:
if we want to write this in minutes, then:
we know that one hour has 60 minutes, then 0.096 hours has:
0.096h*60mins/1h = 5.8 minutes.
then Lewis needs 5.8 minutes in order to cover 16 miles if his speed is 156 miles per hour.
