The only two forces acting on a body have magnitudes of 20 n and 35 n and directions that differ by 80â°. the resulting acceleration has a magnitude of 20 m/s2. what is the mass of the body? a. 2.4 kg b. 2.2 kg c. 2.7 kg d. 3.1 kg e. 1.5 kg

The mass of the body is 2.2 kg.

Explanation:

Given that,

Force acting on a body 1,

Force acting on a body 2,

Direction,

Acceleration,

To find,

Mass of the body.

Solution,

Let F is the net force acting on the body. It is given by :

F = 43.22 N

Second law of motion is given by :

F = ma

m = 2.16 kg

or

m = 2.2 kg

So, the mass of the body is 2.2 kg.

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
