Answer:
x = 28
Step-by-step explanation:
Kinetic energy, KE = 0.5 mv^2
Where m is the mass
V is the velcocity
First calculate the kinetic energy of the bullet
Ke = 0.5(0.008 kg) ( 370 m/s)^2
Ke = 547.6 J
547.6 J = 0.5( 74 kg) v^2
<span>V = 3.85 m/s</span>
Answer:
62 Sunday papers were sold
Step-by-step explanation:
Let x represent the number of Sunday papers sold. Then half that many, or x/2, is the number of Friday papers sold. The total revenue from the sales is the sum of products of quantity and price:
1.50 · x + 0.75 · (x/2) = 116.25
Multiplying by 2, this becomes ...
3.00x +0.75x = 232.50
3.75x = 232.50
Dividing by the coefficient of x gives ...
232.50/3.75 = x = 62
The number of Sunday newspapers sold is 62.
