KINETIC ENERGY

-Lets’s say the mass of your marble is 0.5mg and the speed is 6cm/sec, calculate the K.E

-Using the same mass- marble is 0.5 mg, and the speed is 12cm/sec, calculate the K.E

-Using a mass of 0.10mg and the speed is 9cm/sec, calculate the K.E

SPEED

-Use the specified distance of 120cm plus 60 (h) and a time of 3 sec

-Use the specified distance of 120cm plus 60 (h) and a time of 12 sec

-Use the specified distance of 120cm plus 60 (h) and a time of 8 sec

CALCULATE THE AMOUNT OF WORK DONE

-Find the amount of work done if the force to move the marble is 6N… use total distance of coaster

-Find the amount of work done if the force to move the marble is 12N… use total distance of coaster

-Calculate the GPE for the following: GPE= weight times height  weight=0.6 oz  height of coaster…

-Calculate the GPE for the following: GPE= weight times height  weight= 0.16oz  height of coaster…
