Question

On level ground a shell is fired with an initial velocity of 30.0 m/s at 55.0° above the horizontal and feels no appreciable air resistance. Part A Find the horizontal and vertical components of the shell's initial velocity Express your answers in meters per second separated by a comma. PO AQ 0 2 ? VOh, Voy = Voh , Vov = m/s Submit Request Answer Part B How long does it take the shell to reach its highest point? Express your answer with the appropriate units. CHÅR Value O 2 ? Units t = Submit Request Answer Part C Find its maximum height above the ground. Express your answer with the appropriate units.

Answer 1

Given no air will act that when the shell is resistance, so the only the on it. fired, there is grawitional field ! . Von = U. cose = 30 cos 55 mls. ~ H.2 m/s. 9 osine! lo coso vertical component love = Usino = 30 sings = 24.57 mls. ét vertical component At made mum height velocity must be zero. doo ug = Ui - gt ei g vosin 55 g 24.57 9.8 see = 2.50 see. @ Now using the formula h = 4,2 - 2gh . 62 €2657) g h = 29 = 302 - 2x9.8 = 30.8 m I

© During the component since the vertical motion of of velocity grauitional direction. the shell, the horizontal will remain constom constant field working only along - Horizontal distance L - Youxt = 17.2x2.50 m = 43 m. & sorry fried friend I can do only four (4) probleme.
