Answer:
His average speed.
Explanation:
Average speed = Total distance travelled / total time .
In the given case odometer measures total distance travelled . Dividing it by time will give average speed .
Average velocity can not be the answer as it is measured by dividing displacement by time . Displacement here is zero because initial and final point are same . Instantaneous velocity is given by the speedometer . It keeps on changing all the time . It is actually speed at a particular point of time . It can not be average velocity or speed .
Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.
× 
Downward force = 4.9 N
Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;
<em>Acceleration = 16.8 </em><em />
Therefore, the acceleration of the ball is 16.8

Answer:
it will lose 720 joules of heat
Explanation:
just took the test
I believe it is D a magnetic field
Answer:
the answer is
Explanation:
constant acceleration
because when the object's velocity is changing then the object is accelerating or decelerating
as acceleration describe changing of velocity so the answer is constant acceleration
Acceleration is defined as the rate of change of velocity.
Acceleration = (Change in velocity) / time taken
Acceleration = (Final velocity - initial velocity) / time
As the object velocity changes by the same amount in each second, it means the acceleration is constant.
