At t=0, a particle is projected with a speed Vo at angle theta from a cliff point H=100m from ground level as shown. It is seen at time t=2s, having a velocity v(t2)=8i ‐ 11j m/s according to the coordinate system shown. You must use this coordinate system and origin O. a)Find V o, and theta o. b) If the cliff height is H=100m, write a numerical expression for (t2) in unit vector notation. You must use the origin O and then draw r (t2) on the diagram. c)Find R, the horizontal distance the object has traveled when it reaches its highest point.
