Marking brainliest 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.

The period of a pendulum varies directly as the square root of the length of the pendulum and inversely as the square root of the acceleration due to gravity. find the period when the length is 144 cm and the acceleration due to gravity is 980 cm per second squared, if the period is 7pi seconds when the length is 289 cm and the acceleration due to gravity is 980 cm per second squared.
