Option 3.
Neptune Uranus Saturn Jupiter Mars Earth Venus Mercury.
∆v = -5 m/s
∆t = 5 s
a = ∆v/∆t = (-5 m/s)/(5 s) = -1 m/s^2 .
I know that's the right answer.
I THINK that's what choice-B is trying to say.
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.
<h3>What is acceleration?</h3>
The term acceleration has to do with the rate at which velocity changes with time.
We have to take the moments at the tipping point of rotation as follows;
Clockwise moment = Anticlockwise moment
Hence;
F₂ * 1.58 m = F₁ * 0.67 m
The weight at half the width= 30 cm or 0.3 m
Height of refrigerator = 158 cm 0r 1.58 cm
Then;
m * a * 1.58 = m * 9.81 * 0.30
a = 1.86 m/s²
In order for the refrigerator not to tip over, the maximum acceleration of 1.86 m/s² must not be exceeded.
