Every few years, different countries compete in a sailboat race called the America's Cup. The boats sail over the same distance. Besides distance, what else is needed to find out the speed of each boat in the race?
3 answers
Besides distance, the time taken by each boat to complete the race is needed to determine the speed of the boats. The speed of a boat can be calculated by dividing the distance covered by the time taken to cover that distance. Therefore, in addition to the distance, the time taken by each boat to sail the same distance is essential to calculate their respective speeds.
The picture shows a ball rolling up a ramp. Which statement best describes the motion of the ball?
To provide a precise answer, I would need the picture or additional information about the situation. Without visual representation or specific details, it is difficult to accurately describe the motion of the ball rolling up a ramp. However, generally speaking, when a ball rolls up a ramp, its motion will be characterized by an initial slower speed, overcoming the force of gravity, and eventually gaining momentum and speed as it progresses up the ramp.
