A 3 ky potato is fired directly horizontally from a cliff 196 m tall The potato lands 500 m away. Air resistance is negligible 5. How long was the potato in the air? Given(s) Unknown(:) Equation(:) Substitution(9) Solution(s) 6. Determine the initial horizontal velocity of the potato when it was launched. Substitution(9) Solution(9) Given (9) Unknown() Equation(3) A generator oscillates and pumps out waves as shown to the right. The horizontal scale is in meters. 7. What is the wavelength of the waves being generated? t=25 1: 4s 8. What is the period of the oscillation? You see lightning strike 450 m away, then hear thunder roll. The sound 0.0 1.2 1.8- 2.4 30 wave the lightning strike produces has a frequency of 225 Hz. How much time would it take for the sound (v =343 m/s) of the thunder to reach you? Unknown(=) Equation(=) Substitution (9) Solution(:) Given(9) 10. What is the wavelength of the soundwave (v = 343 m/3) generated by the lightning? Unknown(:) Equation(:) Substitution(9) Solution(9) Given (9)
