Answer:
63.5496631543
Step-by-step explanation:
As you already written, you have to use Newton's law

where F is the force, m is the mass, and a is the acceleration.
You already know the mass and the force, so you have to solve the equality for the acceleration:

plug the given values:

Answer:
4π/3 square units
Step-by-step explanation:
Triangle XYZ is equilateral,
The central angle of the sector is 120°, or 2π/3 radians.
The area of a sector of central angle β is given by
.. A = (1/2)r^2*β . . . . . . β in radians
.. A = (1/2)*2^2*(2π/3) = 4π/3 square units
