35. A body is projected vertically upwards with a 45. For velocity of \( 98 \mathrm{~m} / \mathrm{s} \). How high will it rise and how much time will it take to return to its point of projection? [ \( \mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2} \) ] [2 Marks]
Ans: \( 490 \mathrm{~m}, 20 \mathrm{~s} \)
