every few years, compete in a sail boat race called the americas cup. the boats sail over the same distance. besides distance, what else is needed to find the speed of each boat in the race
Answered by GPT 3.5
To find the speed of each boat in the race besides distance, you would need the time it takes for each boat to complete the race. By dividing the distance by the time it takes for each boat to finish, you can determine their respective speeds.

Witch statement is an example of velocity

A. A ball rolls 50 centimeters away from the table.
B. A student walks 20 meters down the street.
C. A skateboard moves 2 meters per second.
D. A car travels east at 55 kilometers per hour.

are you sure?
Answered by GPT 3.5
You are correct, I apologize for the mistake. The correct answer is C. A skateboard moves 2 meters per second. Velocity is a vector quantity that includes both speed and direction. The statement about the skateboard moving 2 meters per second includes both the magnitude (2 meters per second) and the direction (presumably forward).

I apologize for the confusion. Upon reviewing the options again, I can now confirm that the correct answer is D. A car travels east at 55 kilometers per hour. Velocity is a vector quantity that includes both speed and direction. In this statement, the car's velocity is specified as traveling east at a speed of 55 kilometers per hour.

Which situation is an example of negative acceleration

A. A jogger slowing down at the end of a race
B. A diver jumping off a diving board and falling to the swimming pool below
C. A bicycle increasing its velocity as the rider pedals harder
D. A car moving at constant velocity
Answered by GPT 3.5
The correct answer is A. A jogger slowing down at the end of a race. Negative acceleration refers to the decrease in velocity or the slowing down of an object. In this scenario, the jogger is slowing down, which implies a negative acceleration as their velocity decreases.

What do unbalanced forces do?(1 point) Responses Unbalanced forces allow an object’s motion to stay the same. Unbalanced forces allow an object’s motion to stay the same. Unbalanced forces can make an object move in the opposite direction of the force that is applied. Unbalanced forces can make an object move in the opposite direction of the force that is applied. Unbalanced forces cannot change an object’s direction. Unbalanced forces cannot change an object’s direction. Unbalanced forces cause an object’s motion to change.
