1.in order for work to be done, an applied force must cause a change in the of an object 3.identify each type of energy as mechanical or non-mechanical. (5 points) gravitational potential energy kinetic energy nuclear energy chemical energy electrical energy a. non-mechanical b. mechanical 5.a car has a kinetic energy of 4.32 x 10^5 j when traveling at a speed of 23 m/s. what is its mass? (show all work and include units of measure) 7.set hill 1 to 100 cm, hill 2 to 0 cm, and hill 3 to 0 cm. be sure the coefficient of friction is set to 0.00. run the simulation with each of the 3 cars (35 g, 50 g, and 100 g) then write a brief description of how the final speed differed for each car. (2 points) 8.turn on show graph and select k vs t to see a graph of kinetic energy (e) versus time. click play and observe the graph as the car goes down the track. set hill 1 to 100 cm, hill 2 to 0 cm, and hill 3 to 99 cm. click play. a. what happens to kinetic energy as the car goes down the hill? b. what happens to kinetic energy as the car goes up the hill? (2 points) 10.using the parameters set in question 9, calculate what the final velocity would be at the bottom of the hill using (1/2)mv^2 = mgh (show all work and include units of measure)
