For the following questions, begin with the work-energy equation, cancel terms, substitute and solve.1. A glider is gliding through the air at a height of 416 meters with a speed of 45.2 m/s. The gliderdivesto a height of 278 meters. Determine the glider's new speed. KEi + PEi + Wext = KEf + PEf2. A box with mass m is sliding along on a friction free surface at 9.87 m/s at a height of 1.81 m. Ittravels down the hill and then up another hill. a. Findthe speed at the bottom of the hill. KEi + PEi + Wext = KEf + PEf
