An Olympic diver springs off of a high dive that is 3 m above the surface of the water. When she lands in the water she is trave
klemol [59]

Answer:u=4.51 m/s\ at\ angle\ of\ \theta =59.34^{\circ}

Explanation:

Given

height of building h=3 m

Landing velocity of diver v=8.90 m/s at an angle of 75^{\circ}

Let u be the initial velocity of diver at an angle of \theta with horizontal

Since there is no acceleration in horizontal direction therefore horizontal component of velocity will remain same

u\cos \theta =8.9\cos (75)        ---- -----1

Considering Vertical motion

v^2-u^2=2as

here v=8.9\sin (75)

u=u\sin \theta

s=3 m

a=9.8 m/s^2

(8.9\sin (75))^2-(u\sin \theta )^2=2\times 9.8\times 3

u\sin \theta =\sqrt{(8.9\sin 75)^2-(2\cdot 9.8\cdot 3)}

u\sin \theta =3.886         ----------------2

Divide 2 and 1 we get

\tan \theta =\frac{3.886}{8.9\cos (75)}

\tan \theta =1.687

\theta =59.34^{\circ}

Thus u\cos (59.34)=8.9\cos (75)

u=4.51 m/s
