The object is moving at a constant speed and towards the point of origin.
<h3>What is the distance time graph?</h3>
The distance time graph is used to show the relationship between the distance covered and the time taken. We know that the slope of the distance time graph is known as the speed of the object.
Given the fact that uniform or constant speed occurs when the distance is changing by equal amounts in equal time intervals, it is clear that is we have a straight line graph, the object is moving at a constant speed.
A good look at the graph as shown implies that the object is moving at a constant speed and towards the point of origin.

Answer:
Gravitational potential energy
Explanation:
Gravitational potential energy is the type of energy an object has due to its position in a gravitational field. Water behind a dam possesses gravitational potential energy due to it being at a higher level than the water on the other side of the dam. When the water falls the gravitational potential energy is converted to kinetic energy, leading to the turning of the turbines to generate electricity.
Answer: Noah's speed is 20km/hr
Explanation:
Given;
Final Distance between them at 5pm =320km
Time of travel = 5pm - 1pm = 4 hours
Let x represent Noah's speed
The Ryan's speed = 3x
Total distance between them in 4hours given that they are traveling at opposite directions is.
Distance = speed × time
(x + 3x) × 4hours = 320km
4x × 4 hours = 320km
x = 320km/(4×4hours)
x = 20km/hr
Noah's speed is 20km/hr
Answer:
F = 852 N
Explanation:
We apply Newton's second law to the trailer :
F = m*a Formula (1)
F : net force exerted by the truck on the trailer Newtons (N)
m : mass of the trailer in kilograms (kg)
a : acceleration of the trailer in meters over second square (m/s²)
Data
a=1.20 m/s² : acceleration of the trailer
m=710 kg : mass of the trailer
We replace data in the Formula (1) to calculate the net force exerted by the truck on the trailer
F = (710 kg)*(1.20 m/s²)
F = 852 N
I mean i guess its the metric system?
