the vertical speed v = 55 sin70° - 9.8t
find t when v=0. That is when the max height occurs
(A) 55 cos70° * t
(B) if hit at height h, then y = h + (55 sin70°)*t - 4.9t^2
(C) solve for y=0
6) Mythreyan, a baseball player leads off the game and hits a long home run. The ball leaves the bat at an angle of 70.0o from the horizontal with a velocity of 55.0 m/s.
a. How far will it travel in the air?
b. What is its maximum height?
c. How much time does it spend in the air?
2 answers
A) use 2 t, it also comes down from the peak.
C) is 2 t assuming batter is short
C) is 2 t assuming batter is short
