Answer:
Equivalent resistanfe in parallel (R):
1/R = 1/100 + 1/200 + 1/300
1/R = (6 + 3 + 2)/600
1/R = 11/600
R = 600/11 = 54.55 ohms
Based on Newton's second law:
Force = mass x acceleration
For this problem: we have the mass = 1232 kg and the acceleration = 2 m/s^2
So, just substitute with the givens in the above equation to calculate the force as follows:
Force = 1232 x 2 = 2464 Newtons
