You are in a large parking lot and you've lost your car! On your keys, you have a button to make your car honk its horn. You know that the sound of your horn has a frequency of 350Hz and that the wavelength of the sound
waves is 0.25m. Being a bright and competent physics student, you
obviously open the timer and calculator apps on your phone and perform
a little experiment. If it takes 0.50 seconds for you to hear the sound of
your horn, how far away is your car?

During your summer internship for an aerospace company, you are asked to design a small research rocket. the rocket is to be launched from rest from the earth's surface and is to reach a maximum height of 910 m above the earth's surface. the rocket's engines give the rocket an upward acceleration so it moves with acceleration of 16.0 m/s2 during the time t that they fire. after the engines shut off, the rocket is in free fall. ignore air resistance.

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.
