Answer:
kinetic energy of glider = -0.376 j
Explanation:
Original distance by which the spring is compressed can be determine by using law of conservation of energy (As spring slide from glider, it gain some potential energy. On the top of track there is glider’s potential energy exist)
where x is compressed distance by spring
height of track is calculated as
where l is distance covered by glider, theta angle is the angle of inclination of track
therefore, we have formula for x as
x = 0.039 m
kinetic energy of glider = potential energy by spring - potential energy at 1.50 distance
kinetic energy of glider = -0.376 j
