Question

if in ∆ Win and ∆ Fly
ar (Fly) = 98 sqcm and WN = 5/7 then ar (Win) = ? sqcm
options (9, 18, 42 , 49)​

Answer 1

Answer:

Explanation:

The correct answer is B.

Given,

v=98m/s,t=10s

The vertical component and the horizontal component of velocity with it will hit the ground.

so, considering for vertical motion, velocity 10s

v=0+gt

so,

v=9.8×10

=98m/s

so,

The angle made with the ground while hitting is  tan  

−1
