A body is moving toward vertical direction with the velocity V = (a-bt)(c-dt), where t is the time, a=0.427(m/s)1/2 b=0.272m 1/2-3/2,c=3.50m 1/2-1/2, and d=0.387m 1/25-3/2 are constants. At the time t = t.-1.84s the vertical coordinate y of the body is y:=3.52m. What is the potential energy of the body when the time is t:-3.08s? Zero level of potential energy corresponds to y = 0. Input your answer in J using 3 significant figures. The mass of the body is 1 kg. g=9.80 m/s²
