Q8. The 0.8-kg ball is connected to a rigid rod with negligible mass. It is released from rest at the position shown in the image below and later the rod becomes vertical. The spring is initially unstretched and has a spring constant k = 4.8 N/m. The dimensions are a = 0.7 m and b = 0.8 m. If at the initial state the total potential energy of the ball is 0, determine the total potential energy of the ball when the rod becomes vertical. Negative sign must be included if the energy is negative. Please pay attention: the numbers may change since they are randomized.

Q8. The 0.8-kg ball is connected to a rigid rod with negligible mass. It is released
from rest at the position shown in the image below and later the rod becomes
vertical. The spring is initially unstretched and has a spring constant k = 4.8 N/m. The
dimensions are a = 0.7 m and b = 0.8 m. If at the initial state the total potential
energy of the ball is O, determine the total potential energy of the ball when the rod
becomes vertical. Negative sign must be included if the energy is negative. Please
pay attention: the numbers may change since they are randomized. Your answer
must include 1 place after the decimal point, and proper Sl unit. Take g = 9.81 m/s².
