I would say A Because it weighs more than the water
<span>7.21 ft/s^2
Since you're looking for average acceleration, you can simply divide the change in velocity by the time. To make the calculation more reasonable, first convert the speed of 173 mi/h into ft/sec by multiplying by 5280 to convert from mi/h to ft/h and then dividing by 3600 to convert from ft/h to ft/s.
173 * 5280 / 3600 = 253.7333 ft/s
Now divide the change in velocity by the time in seconds.
253.7333 ft/s / 35.2 s = 7.208333 ft/s^2
Rounding result to 3 significant figures gives 7.21 ft/s^2</span>
Answer:
Mass, m = 665.77 kg
Explanation:
The question says that "If you try to smuggle gold bars by filling your backpack, whose dimensions are 56 cm * 28 cm * 22 cm, what would be its mass?
"
The dimension of gold bar is 56 cm×28 cm×22 cm
We know that the density of gold is 19.3 g/cm³
The mas per unit volume of a material is called its density. It can be given by :

So, the mass of the gold bar is 665.77 kg.
