I have home work that I cannot understand, it relates to kinetic energy, and energy potential I cannot find the formula to use to solve it
Heres some of the questions
1.An elastic band is stretched a distance of 15.0cm by a force of 10.0N
A.How much potential energy is stored in the elastic.- I don't understand how to find that out.
2. A 1.00 g object is placed on the elastic, and the elastic is released in a vertical direction. How much energy was transferred to the object by the elastic? Can't figure out how to solve.
A.What was the speed of the object as it leaves the elastic? Don't know the formula
B.How high will the object rise (assume no friction)- Don't know the formula
Please help me solve these questions as this assignment is due tommorow.
And sorry I couldn't show any work I've done, because I cannot figure out where to start with these
questions.
