Answer:i belive the answer is E = 1/2 mv^2
hope this helps plz mark me as braliest
Forget the numbers and think about how speed works for a second. If a plane flies at 600km/h, this means that it will fly exactly 600 km in 1 hour. So, how long would it take to fly 2400 km??
2400/600 = 4hours.
Do this for all three and add up the hours.
Total time: 12 hours
Average speed is the total distance / total time.
So,
Add up all the distances and divide by 12.
(2400+1200+2500) / 12
Average speed: 508.33333333 km/h
Vectors have both size and direction.
Vectors are indicated with arrows.
Vectors can have positive or negative values.
Answer:
Centripetal force is defined as, "the force that is necessary to keep an object moving in a curved path and that is directed inward toward the center of rotation.
Explanation:
Just a few examples are the tension in the rope on a tether ball, the force of Earth's gravity on the Moon, friction between roller skates and a rink floor, a banked roadway's force on a car, and forces on the tube of a spinning centrifuge. Any net force causing uniform circular motion is called a centripetal force.
Two things are said to be in contact if the smallest distance between a point in one of them and a point in the other one is zero.
