You throw a ball vertically upward. which statement best describes the direction and magnitude of the ball's acceleration while the ball is still moving up? upward, constant magnitudeupward, increasing magnitude upward, decreasing magnitudedownward, constant magnitudedownward, increasing magnitudedownward, decreasing magnitudezero acceleration

The rearrangement of particles in a physical change. hope this

Initial velocity,  u = 4.9 m/sfinal velocity = v m/sinitial height,  h₁ =  245 m    final height, h₂ = 0a = -9.8  m/s²time taken = t secondss = ut + 0.5at²⇒  (h₂-h₁) = ut + 0.5at²⇒  0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get   t = 7.59sv  = u +  at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is  69.48 m/s downward

Inner peace.. jk it's  a stable electron configuration
