013 (part 1 of 2) 10.0 poin A model airplane of mass 1.1 kg is attached
to a horizontal string and flies in a horizontal
circle of radius 5.3 m, making 1.2 revolutions
every 8 s. (The weight of the plane is balanced
by the upward "lift" force of the air on the
wings of the plane.)
The accelaration due to the gravity is 9.81
m/s
Find the speed of the plane.
Answer in units of m/s.

Find the tension in the string.
Answer in units of N

We all use gps today, even if we don't drive yet. i bet you have been in the car with a parent and they have asked you to get out your phone to find a specific location. in your car, on the phone, you are using a very sophisticated technology. gps satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. gps receivers take this information and use trilateration to calculate the user's exact location. essentially, the gps receiver compares the time a signal was transmitted by a satellite with the time it was received. the time difference tells the gps receiver how far away the satellite is. now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map. what type of signal is utilized by the gps satellite?

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?

With i really need the correct answer!
