The ball has travelled a total distance of 18 feet after dropping and rebounding.
After being dropped for the first time, the ball will rebound to a height of 3 feet as it returns to half its original height. The geometric series formed by the total distance travelled while falling and rebounding has a common ratio,
r = 0.5
6 ft + 3 ft = 9 ft will be the first term in the series
For the sum formula S = ,
substitute a = 9 and r = 0.5 to get the ball's total distance travelled.
S =
S =
S = 18
The ball has therefore travelled a total of 18 feet.

Watch in the diagram above that a downward vector will provide a partial or full cancellation of an upward vector.
And a leftward vector will provide a partial or full cancellation of a rightward vector.
In this case, as the meanings of the vectors are opposite, one of the forces receives the negative signal and thus a piece of the other vector is drawn, as shown in the figure. And to know the module of the resultant force, if it subtracts the modules of the forces.
Answer:
(in order to have a net force of 8 N, right) B. 8 Newtons
Answer:
The potential energy change is 0.596 J.
Explanation:
Given that,
Potential difference =14.9 V
Charge q =0.0400 C
We need to calculate the change potential energy
The potential energy change is the product of the charge and potential difference.
Using formula of change potential energy
Hence, The potential energy change is 0.596 J.
Choices 1,3,4 are supported.
Choice 2 is incorrect because a horizontal slope on a position time graph means the object is starionary.
Choice 5 is incorrect because the speed of an individual can be determined by calculating the slope at a point on the position time graph.
Answer:
The correct option is;
Technician A only
Explanation:
Leaks in the cooling system parts such as the radiator cap can be tested with a pressure operated hand pump by attaching the pump cap to the pump with an adaptor and apply pressure enough for there to be a release of pressure at the cap.
The pressure added to the system should be maintained for up to two minutes. If the pressure drops quicker, then there is likely to be leaks in the system
The freezing and boiling point of the coolant is measured with an antifreeze tester which carries the appropriate apparatus to measure the coolants freezing and boiling points.
