The formula for calculating the minimum velocity needed for a ball to go up a step is v = √(2gh), where v is the velocity, g is the acceleration due to gravity, and h is the height of the step.
The height of the step can be determined by measuring the vertical distance between the ground and the top of the step.
The hint provided in this problem is important because it helps to guide the calculation process by providing a starting point and indicating which variables should be used in the formula.
Yes, this problem can be solved using different units of measurement. However, it is important to ensure that all units are consistent and in the correct form (e.g. converting feet to meters if necessary) in order to get an accurate answer.
Yes, there are several real-world applications for this problem, such as calculating the minimum speed needed for a rollercoaster to clear a loop, or determining the minimum takeoff speed for an airplane to clear an obstacle.
