Answer: 146.12 m/s (to the right)
Step-by-step explanation:
The Conservation of Linear Momentum principle states that the initial momentum
(before the elastic collision) must be equal to the final momentum
(after the elastic collision):
(1)
Being:
Where:
is the mass of the racket
is the velocity of the racket before the collision
is the mass of the ball
is the velocity of the ball before the collision
is the velocity of the racket after the collision (assuming it is at rest after hitting the ball)
is the velocity of the ball the collision
So, we have the following:
(2)
Finding
:
(3)
(4)
Finally:
This is the velocity of the ball after the collision
Answer:
$187
Step-by-step explanation:
$10,295 - $2,295 = $8,000
Price of car = $8,000
4 years is 48 months
$8,000 x 12% = $8,960
$8,960 / 48 = 186.67
round up to $187 a month
If you would like to know the sum of the geometric sequence, you can calculate this using the following steps:
3, 15, 75, 75 * 5 = 375, 375 * 5 = 1875, 1875 * 5 = 9375, 9375 * 5 = 46875, 46875 * 5 = 234375
<span>3 + 15 + 75 + 375 + 1875 + 9375 + 46875 + 234375 = </span>292,968
The correct result would be 292,968.
