Kelli and Jarvis are members of the stage crew for the Variety Show. Between acts, they must quickly move a Baby Grand Piano onto stage. After the curtain closes, they exert a sudden forward force of 524 N to budge the piano from rest and get it up to speed. The 158-kg piano experiences 418 N of friction. a. What is the piano's acceleration during this phase of its motion?b. If Kelli and Jarvis maintain this forward force for 1.44 seconds, then what speed will the piano have?
