The next test involves the performance of the new battery. The robot encounters an obstacle on his journey. Using its arm it applies a force of 35N at an angle of 25 below horizontal and is able to displace the object for 20m in a time of 65s. At the beginning of the test the battery's is displaying a total stored energy (ability to perform mechanical work) of 2500 Nm. What would be the remaining energy displayed at the end of the test? Useful formula: AE =W (change in available energy is equal to the work done)
