When the speed booster is set up horizontally at the edge of a table (h=1.11 m) it sends a toy car of mass m=0.06kg in the projectile motion, so that it lands at horizontal distance of x1=1.36 m away from the edge of the table.
When the sam car with the same speed booster are used but the car is made to go through the loop-the-loop track before it is send away from the edge of the table, it lands
at distance x2=1.08.
Use this information to find the energy lost by the car while making the vertical loop
