An object with mass 0.900kg on a frictionless, horizontal surface is attached to this spring, pulled a distance 1.00m to the right (the x – direction) to stretch the spring, and released. What is the speed of the object when it is 0.50m to the right of the x
Answer:
7.85 m/s
Explanation:
We are given that
Mass of object=m=0.900 kg
U=0 when x=0
Potential energy=
Substitute the values
Using the formula
Substitute x=0
Using law of conservation energy
Substitute the values
