lys-0071 [83]

Answer: the maximum heigth of the stadium at ist back wall is 151.32 ft

Explanation:

1. use the position (x) equation in parobolic movement to find the time (t)

565 ft = [frac{176 ft}{1 s\\}[/tex] * cos (35°)  * t

t= 3.92 s

2. use the position (y) equation in parabolic movement to find de maximun heigth  the ball reaches at 565 ft from the home plate.

y= [[frac{176 ft}{1 s\\}[/tex] * sen (35°) * 3.92 s] - \frac{32.2 ft/s^{2} *3.92 s^{2}  }{2}

y= 148.32 ft

3. finally add the 3 ft that exist between the home plate and the ball

148.32 ft + 3 ft = 151.32

The speed of a transverse wave on a string is 450 m/s, and the wavelength is 0.19 m. The amplitude of the wave is 1.6 mm. How mu
tigry1 [53]

Answer: 2.22s

Explanation: wave speed = 450 m/s, A = amplitude = 1.6mm, λ= wavelength = 0.19m

Wave speed = distance traveled / time taken

Distance traveled = 1km = 1000 m

450 = 1000/ t

t = 1000/ 450 = 2.22s
