Answer:-2.61 m/s
Explanation:
This problem can be solved by the Conservation of Momentum principle, which establishes that the initial momentum 
must be equal to the final momentum 
:
(1)
Where:
(2)
(3)
is the mass of the first car
is the velocity of the first car, to the North
is the mass of the second car
is the mass of the second car, to the South
is the final velocity of both cars after the collision
(4)
Isolating :
(5)
(6)
Finally:
(7) This is the resulting velocity of the wreckage, to the south
Answer:
Answere is (D)
Explanation:
Given m1, v and m2
Total circular momentum is conserved: total circular momentum before putty coin collision is equal to total circular momentum after collision.
Let the final circular velocity of the system be V. Initial circular velocity of the putty is zero.
m1v + m2× 0 = (m1 + m2) V
V = m1v/(m1 + m2).

As the energy goes up, the frequency goes ------
As the energy goes up, the frequency goes up. The higher the energy goes up, it determines the frequency ( how big the wave is).
Hope I helped :D
From the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.
<h3>How long will it take to travel 363.0 miles at the given average velocity? </h3>
Note that; Velocity is the speed at which an object moves in a particular direction. It is expressed as;
v = distance / time
Given that;
- Distance covered by the car d = 263.0 miles
- Time elapsed t = 5.5 hours
First we determine the velocity of the car.
v = distance / time
v = 263.0 miles / 5.5 hours
v = 47.8181 miles per hour.
Now, if the car travels 363.0 miles, time elapsed will be;
velocity = distance / time
time = distance / velocity
time = 363.0 miles / 47.8181 miles per hour
time = 7.6 hours
Therefore, from the average velocity calculated, if the car should travel 363.0 miles, the time elapsed will be 7.6 hours.
