Distance covered, s = 8ft - 4ft = 4 ftinitial velocity, u = 34 ft/sthe acrobat is moving upwards and therefore, a = -g = -9.81 m/s^2 = 32.19 ft/s^2applying equation of motion; s = ut -1/2gt^2then,4 = 34t -1/2*32.19t^24 = 34t - 16.095t^2rearranging; -16.095t^2 + 34t - 4 = 0solving the quadratic equation; t = {-34 +/- sqrt [34^2 - 4(-16.)]}/2(-16.095) = 1.06 +/- 0.93 = 0.13 or 1.99the acrobat will take 0.13 seconds to be at 8 ft above the ground. additionally, once at the maximum height, the acrobat will move down and be at the same spot (that is height) after 1.99 seconds moving down.

Hello @mmmhhbhb,how are you doing? i will answer each question individually below! i hope it ! remember to contact me if you need further assistance!   1. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.30 m? 100 hz x .30 m = 30 m/s2. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 0.10 m? 50 hz x .10 m = 5 m/s3. what is the frequency of a wave that has a wave speed of 20 m/s and a wavelength of 0.50 m? 20 m/s divided by .50 m = 40 hz4. what is the frequency of a wave that has a wave speed of 80 m/s and a wavelength of 0.20 m? 80 m/s   divided by .20 m = 400 hz5. what is the frequency of a wave that has a wave speed of 120 m/s and a wavelength of 0.40 m? 120 m/s divided by .40 m = 300 hz6. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 440 hz? 340 m/s divided by 440 hz = .77 m7. what is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 hz? 340 m/s divided by 880 hz = .38 m8. what is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 hz? 250 m/s divided by 400 hz = .63 m9. what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 2.0 m? 50 hz x 2.0 m = 100 m/s10. what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.50 m? 100 hz x 0.5 m = 50 m/sthat's all, hope i !   you,  darian d.
