Two men pull on a 31-kg box with forces 8.3 N and 6.6 N in opposite directions.
kykrilka [37]

The resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.

The given parameters:

  • Mass of the box, m = 31 kg
  • Two applied forces, = 8.3 N and 6.6 N

<h3>Resultant force on the box</h3>

The resultant force on the box is calculated as follows;

F_{net} = F_1 - F_2\\\\F_{net} = 8.3 \ N - \ 6.6 \ N\\\\F_{net} = 1.7 \ N

<h3>Resultant acceleration of the box</h3>

The resultant acceleration of the box is calculated as follows;

F = ma\\\\a = \frac{F}{m} \\\\a = \frac{1.7}{31} \\\\a = 0.055  \ m/s^2

Thus, the resultant acceleration of the box is 0.055 m/s² in the direction of the greater force.

A motorcycle running on gasoline wastes a large amount of energy mainly as A) heat energy and sound energy. B) light energy and
vlada-n [284]

A motorcycle mainly wastes energy as heat <u>energy</u> and <u>sound</u> energy. In the engine, chemical energy is transformed into mechanical energy. However, the engine is inefficient and much of the chemical energy is lost as heat energy. Also, some of the energy is transformed to sound energy. This explains why the motorcycle is noisy and has an exhaust pipe.
