Final answer:
To predict the time for a steel sphere to roll down an incline, we can use the principles of physics, specifically the conservation of energy.
Step-by-step explanation:
To predict the time for a steel sphere to roll down an incline, we can use the principles of physics, specifically the conservation of energy. When the sphere rolls down an incline, the potential energy is converted into kinetic energy. The equation to calculate the speed of the sphere is:
v = sqrt(2gh)
Where v is the final speed, g is the acceleration due to gravity, and h is the height of the incline.
