1.	16. A ball is thrown vertically upwards and reaches a maximum height in 3 sec Calcula a. The velocity with which it was thrown upwards.b. Maximum height attained by the ball.
Answer» a is 30 and B is 135 Explanation:t=u/g that is 3sec=X/g g= 10 so x =30 s=ut+1/2at2 u=30 t=3 a=10 so s=30×3+1/2×10 32 =135
