A freely falling body travelled 35 m in last second of its journey :-

Options:(select one or more)

Answer:

A, B, C

Solution:

Given $H - H^{'} = 35$ $\frac{1}{2} g n^{2} - \frac{1}{2} g (n - 1)^{2} = 35$ $n = 4$ $H = \frac{1}{2} g \times 4^{2}$ $= 5 \times 16 = 80 m$ $v = u + gt$

$= 0 + 10 \times 4 = 40 m / s$
