Exercise: Chapter 1, 2 and 3 1. Figure below shows two coplanar vectors lying on the x-y plane act on a particle P. 70 D=80 cm x P C=60 cm Calculate the magnitude and direction of the resultant vector at point P.(0.82 m,23.10 ) 2. A body is projected with a velocity of 200 m s" at an angle of 30% above the horizontal. Calculate a) the time taken to reach the maximum height, (10.2 s) b) its velocity after 16s.( 203.6 m s-])
