suppose 1 gold bar is 6 cm long, 2 cm high, and 3 cm wide. how many whole gold bars will you be able to fit in a vault with a vo
Gemiola [76]
To determine the number of gold bars that would fit in the vault, determine the volume (v) of a single gold bar.
                              v = l x h x w
where l, h, and w are length, height and width, respectively. Substituting the known values, 
                            v = (6 cm)(2 cm)(3 cm) = 36 cm³
The number of gold bars can be determined by dividing the volume of the vault by the volume of the gold bar,
                                      n = (500 cm³ / 36 cm³) = 13.89
Thus, the maximum number of gold bars in the vault is 13.

A drag racing vehicle travels from 0 to 100mph north in 5 seconds. What is the acceleration
kap26 [50]

The acceleration of the car is 8.9 m/s^2

Explanation:

The acceleration of an object is given by

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time elapsed

Here we have to convert the initial and final velocity of the vehicle into SI units. So we have:

u = 0 is the initial velocity

v=100 mph \cdot \frac{1609 m/mi}{3600 s/h}=44.7 m/s is the final velocity

t = 5 s is the time elapsed

Solving for a, we find the acceleration:

a=\frac{44.7-0}{5}=8.9 m/s^2
