Explanation:
The instantaneous velocity of a point mass that executes a simple harmonic movement is given by:

Where:

Express the amplitude in meters:

The angular frequency can be found using the next equation:

Using the data provided:

At the equilibrium position:


Answer:
the force of the plow pulling backward on the tractor
Explanation:
Answer:
Centre of mass of any body is a point where all mass of a body is supposed to be concentrated
it lies in geometrical centre....
This problem is to let you practice using Newton's second law of motion:
Force = (mass) x (acceleration)
-- The airplane's mass when it takes off (before it burns any of its load of fuel) is 320,000 kg.
-- The force available is (240,000 N/per engine) x (4 engines) = 960,000 N.
-- Now you know ' F ' and ' mass '. Use Newton's second law of motion to calculate the plane's acceleration.
