A 260-kg glider is being pulled by a 1,940-kg jet along a horizontal runway with an acceleration of a= 2.20 m/s^2 to the right. Find the following: a. the magnitude of the thrust provided by the jet's engines.
b. the magnitude of the tension in the cable connecting the jet and glider

a) The magnitude of the thrust provided by the jet's engines is 4840 newtons.

b) The magnitude of the tension in the cable connecting the jet and glider is 572 newtons.

Explanation:

a) By Newton's laws we construct the following equations of equilibrium. Please notice that both the glider and the jet experiments has the same acceleration:

Jet

(1)

Glider

(2)

Where:

- Thrust of jet engines, measured in newtons.

- Tension in the cable connecting the jet and glider, measured in newtons.

, - Masses of the glider and the jet, measured in kilograms.

- Acceleration of the glider-jet system, measured in meters per square second.

If we know that , and , then the solution of this system of equations:

By (2):

By (1):

The magnitude of the thrust provided by the jet's engines is 4840 newtons.

b) The magnitude of the tension in the cable connecting the jet and glider is 572 newtons.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
