Question

Part C:Analyzing KE datatables Analyze the following data tables containing KE DATA, Identity which data is consistent with an object that is SPEEDING UP, which one is consistent with an obiect that in SLOWING DOWN, which one is consistent with an object that moving at a CONSTANT SPEED. and which one is consistent with an abject that is AT REST. You will only Hosive credit when all four have been chosen correctly. Time (S) KE(J) 100 200 300 14 4233 23 : Time (s) KE (J) 0 25 0 50 0 75 0 Time (9) KE (J) 64 1 67 2 77 3 80 Part D:Analyzing PE data tables Analyze the following data tables containing PEG DATA. Identity which data is consistent with an object that is MOVING UP, which one is consistent with an object that is MOVING DOWN, which one is consistent with an object that is maintaining a CONSTANT NONZERO ALTITUDE, and which one is consistent with an object that is ON THE GROUND.

Answer 1

Parta The object in spuding up → KE will increase Slowing down - K E dureases with time constant speed - KE. constant at rest ok.E. In first data Answers are T o loo Loo 300 oo 7 7 KE is decreasing K.E I with 44 42 time. 33 23 Hence slowing down. 2 dara KE. in contant 823 J constant speed data 3. KE. o → at ret data 4 64 67 77 80 - → KE increasing object speeding up-

Part D when object moes up → PE increases moves down → 'PE dureares constant nonzero actitude Pe. constant at ground - PE =0 Correct answers are. Data I 69 65 6053 - moving down Jooo at, og er und Data 3 4352 60 69 → Dara a 98 98 98 98 moving up → at constant nonzero cultitude
