ANSWER: 38.72 m/s
Explanation: By using parallelogram law,w2 =u2 + v2 + 2uv cos(a)Where,w = magnitude of resultant velocityu = magnitude of first velocityv = magnitude of second velocitya = angle between first and second velocity
ANSWER: 44.27 m/s
Explanation: No other than gravitational force is acting upon the object. Thus by using motion equation v2 = u2+ 2as and taking initial velocity of the object u = 0, we can get the final velocity that is 44.27 m/s.
