Guys, eto na yung PPTs sa bio. Can’t upload the human circulation ppt sa YG, it’s too big. D: So dito nyo na lang idownload. Nasa YG yung gas exchange PPT, though, but I posted a copy here na rin.

guys, eto yung “physics hw”. di sure yung items eh. pero sabi ni kit answer all to be sure xD. paedit/comment if mali ah or pag alam nyo yung specific items na kelangan sagutan. thankshoo.

37. A ball thrown horizontally at 21 m/s from the roof of a building lands 24m from  the base of the building. How high is the building?
44. A hunter aims his gun directly at a monkey hanging from a high tree  branch some distance away. At the instant the gun is fired, the monkey drops from the  branch, hoping to avoid the bullet. Show analytically that the monkey made the wrong  move. Ignore air resistance.
Kit: 47. A projectile is shot from the edge of a cliff 140m above ground level  with an initial speed of 100m/s at an angle of 37.0 degrees with the horizontal. a)  Determine the time taken by the projectile to hit point P at ground level. b)  Determine the range X of the projectile hits point P, find c) the horizontal and the  vertical components of its velocity   , d) the manitude of the velocity, and e) the  angle made by the velocity vector with the horizontal.
Kit:
39. A football is kicked at ground level with a speed of 17.0 m/s at an  angle of 40.0 degrees to the horizontal. How much later does it hit the ground? Ignore  air resistance
Kit: 49. A ball is thrown horizontally from the top of a cliff with initial  speed Vo (at t = 0). At any moment, its direction of motion makes an angle theta to  the horizontal. Derive a formula for theta as a function of time, t, as the ball  follows a projectile’s path
