I. An object is thrown with making thrown with making an angle x with horizontal as shown in figure below . a) If we put the value to u equal to 30mls & x equal to 60o, what horizontal range will be travelled by object. [2] b) what will be the velocity of object after 2 second when velocity of projection is 3 omls and angle with horizontal is 6o. [3] |
