Answer:
Step-by-step explanation:
Let v be the speed after the collision of both the cars.
Now, momentum is given by: mass × velocity, then by equating the total momentum before and after the collision of the two cars, we get
⇒
⇒
⇒
Thus, they are moving at the velocity of
Answer:
in six hours it would be $34.25
Step-by-step explanation:
The computation of the total cost for 6 hours is shown below:
For one hour it would be $8.50
For two hours
= $13.65 - $8.50
= $5.15
For three hours
= $18.80 - $13.65
= $5.15
For four hours
= $23.95 - $18.80
= $5.15
For five hours
= $23.95 + $5.15
= $29.10
For six hours
= $29.10 + $5.15
= $34.25
Hence, in six hours it would be $34.25
Answer:
52
Step-by-step explanation:
13 * 4 = 52
(is * 4 since 4 * 3 months is a year)
