Ground
Compare the total mechanical energy of the car and punger at points A, B,
and
• Explanation:
.
Base your answer to the following question on the information below and on your
knowledge of physics
A gre-powered model airplane has a mass of 2.50 kilograms. A student
exerts a force on a cord to keep the airplane flying around her at a constant
speed of 18.0 meters per second in a horizontal, circular path with a radics
of 25.0 meters
Calculate the kinetic energy of the moving airplane. Show all work, including the
equation and substitution with units]
• Equation: KE = _m_ V^2
• Work: Ke=12*2.50kg*18^2m/s
• Answer w/Units:
