Answer:
a force and a movement in the same direction as the force.
Explanation:
As we know that the formula to find the work done is given by
here if the force is applied at some angle with displacement then in that case
now we know that if the force and displacement is in opposite direction then the work done is negative while if the force and displacement is in same direction then the work done is positive
So work to be accomplished only when the sign of the work done is positive so it must be in the same direction as that of displacement of the object
so correct answer would be
a force and a movement in the same direction as the force.
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.
