Answer:
12 meters per seconds......
Explanation:
60/5=12
Answer:
Friction
Explanation:
Brief elaboration, Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.
Net force acting on the car is 3 x 10^3 Newtons:
Average speed = (distance covered) / (time to cover the distance).
Distance covered = 437 km = 437,000 meters
Time to cover the distance = (7.27 hrs) x (3600 sec/hr) = 26,172 seconds
Average speed = (437,000 meters) / (26,172 seconds)
Average speed = 16.7 m/s
To solve this problem we will apply the concepts related to the kinematic equations of linear motion. Where speed is described as the distance traveled in a given time, and the successive equivalences that can be made under that equation.
The distance traveled by the girl with in the given time is
The distance covered by the boy with in the given time is
Since the boy will travels with twice the speed of the girl
Half way between the two rafts at the beginnings is
The final distance between the two rafts at the instant the boy reached the central point of the line joining between them is
Therefore the distance that there is between the two rafts when the first one reaches the toy is 10.5m
