An airplane accelerates down a runway at 3.20 ms for 32.8 seconds until it finally lifts off the ground determine the distance traveled before takeoff

105 meters.

Explanation:

If the airplane moves with the speed of 3.20 m/s for 32.8 seconds on the ground before takeoff, it covers 105 meters distance on the ground. We can calculate the distance by using the formula of speed which is speed is equal to distance divided by total time taken. We have to remove time present below the distance so for that we have to cross multiply and we get distance equal to speed x time. So by putting the values of speed and time we get our answer.

resonant frequency

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
