A batted baseball is hit with a velocity of 47.3 m/s, starting from an initial height of 8 m. Find how high the ball travels in two cases:
(a) a ball hit directly upward and
(b) a ball hit at an angle of 70° with respect to the horizontal.
Also find how long the ball stays in the air in each case.
case a
case b
I got part a by taking t(top)=Vo/g =4.83 s --> ymax=8m +47.3m/s(4.83s)-.5(9.8)(4.83)^2 = 122.15m
I don't know how to continue the rest of the problem...
