Jawaban dan Penjelasan
Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.
To calculate the resultant force, we need to first find the individual forces exerted by Dini and Rini.
The force exerted by Dini is given by the formula:
F1 = m1 x a1
where
m1 = mass of the mini fridge = 15 kg
a1 = acceleration of the fridge = 3 m/s^2
F1 = 15 kg x 3 m/s^2 = 45 N
The force exerted by Rini is given by:
F2 = m2 x a2
where
m2 = mass of the study table = 25 kg
a2 = acceleration of the table = 6 m/s^2
F2 = 25 kg x 6 m/s^2 = 150 N
Since Dini pushes the mini fridge to the right and Rini pulls the study table to the left, the direction of the forces are opposite. Therefore, we need to subtract the force exerted by Rini from the force exerted by Dini to get the resultant force:
Resultant force = F1 - F2
= 45 N - 150 N
= -105 N
The negative sign indicates that the resultant force is acting in the opposite direction to Dini's force, which means that there is a net force pushing the mini fridge to the left.
