Answer: The force of the engines is 5700N
Explanation:
By the second Newton's law, we have that:
F = m*a
Force equals mass times acceleration.
In this case, we have:
m = 1400kg
a = 3 m/s^2
And the force will be equal to the force of the engines, f, plus the force of the current, -1500 N (because this is pushing you back, so it is in the opposite direction than f), then we have:
F = f - 1500N
Then we have the equation:
f - 1500N = 1400kg*3m/s^2 = 4200N
f - 1500N = 4200N
f = 4200N + 1500N = 5700N
The force of the engines is 5700N
Answer:
true
Explanation:
Series resistors are additive
r1 + r2 + r3 = r total the total will always be greater than any one of the parts
Answer:
Explanation:
more the density , more will be the buoyant force acting on it , less the density less will be the buoyant force acting on it. This is why people float in dead sea and sink in other seas
