H, Please explain and answer this question for me:thank you! Why does the shape of the ramp not affect the Total Energy in the non-friction case and Why does the shape of the ramp affect the Total Energy in the friction case?

An archery bow is drawn a distance d = 0.75 m and loaded with an arrow of mass m = 0.067 kg. The bow acts as a spring with a spring constant of k = 195 N/m, and the arrow flies with negligible air resistance. To simplify your work, let the gravitational potential energy be zero at the initial height of the arrow. a. How fast, in meters per second, will the arrow be traveling as it leaves the bow?  b.  If the arrow is shot at an angle of θ = 45° above the horizontal, how high, in meters above the initial height, will the arrow be when it reaches its peak?

A process occurs in which a system's potential energy decreases while the system does work on the environment. Does the system's kinetic energy increase, decrease, or stay the same? Or is there not enough information to tell? Explain. Match the words in the left column to the appropriate blanks in the sentences on the right. positive negative zero unknown ‒‒‒‒‒‒‒‒‒‒ only the potential energy does the work the system does work on the environment Submit the mechanical energy does not change the change in potential energy may be greater as well as less than the work the system does on the environment the body cannot do more work than the change of its potential energy Request Answer The change in kinetic energy is because Reset Help
