Answer:
Coefficient of static friction will be equal to 0.642
Explanation:
We have given acceleration
Acceleration due to gravity
We have to find the coefficient of static friction between truck and a cabinet will
We know that acceleration is equal to , here
is coefficient of static friction and g is acceleration due to gravity
So
So coefficient of static friction will be equal to 0.642
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.
