Vedclass · Answer

(A) For a projectile motion,if a body passes through a point at time $t_1$ and reaches the ground after a further time $t_2$,the total time of flight is $T = t_1 + t_2 = 2.3 \ s + 5.7 \ s = 8.0 \ s$.The time taken to reach the maximum height is $t_{max} = \frac{T}{2} = \frac{8.0 \ s}{2} = 4.0 \ s$.The maximum height $H$ is given by the formula $H = \frac{1}{2} g t_{max}^2$.Substituting the values: $H = \frac{1}{2} 	imes 10 \ ms^{-2} 	imes (4.0 \ s)^2$.$H = 5 	imes 16 = 80 \ m$.Thus,the maximum height reached by the body is $80 \ m$.

$A$ body projected at a certain angle $(\neq 90^{\circ})$ from the ground crosses a point in its path at a time $t_1 = 2.3 \ s$ and from there it reaches the ground after a further time $t_2 = 5.7 \ s$. The maximum height reached by the body is (Take $g = 10 \ ms^{-2}$) (in $m$)
