20 points DUE TODAY Please help with these 3 questions.

#1 Design an experiment to determine how changing the velocity or mass of an object impacts its kinetic energy. Explain the measurements you’ll make and discuss the number of experimental groups you’ll include and trials you’ll perform. Also identify the independent, dependent and controlled variables.

#2 Below is a cart at different positions along a rollercoaster. Compare the potential energy of the cart at position A, B, C and D. Also, compare the total energy of the cart at position A to position C.

#3Compare the potential energy of an object in space to an object resting on Earth’s surface. Specifically, how would the potential energy of a person on a plane compare to an astronaut traveling on a spacecraft to Mars?
