The surface of a smooth inclined plane of inclination 30° is ABCD. CD is in contact with horizontal ground. A particle is projected parallel to AB from A with a velocity of magnitude u such that it passes through diagonally opposite point C. If AB = BC = 10 m and g=10 ms-2, its initial speed u in ms-1 is?
Answers
Answer:
65 is initially speed
hope it helps you
