Answer:

15 m/s

Explanation:

Initial momentum = final momentum

(25 kg) (15 m/s) + (25 kg) (0 m/s) = (25 kg) (0 m/s) + (25 kg) v

v = 15 m/s

A car with mass m traveling at speed v has kinetic energy k. what is the kinetic energy of a second car that has the same mass m
vampirchik [111]
Kinetic energy, KE, is modeled by the formula KE =  \frac{1}{2}mv^2, where m is the mass in kg and v is the velocity in m/s.

In this scenario, mass and one-half are constant but the velocity changes. 

You can see that by squaring twice the velocity, that is equal to four times the original KE. Therefore, the answer is 4k.

If a car travels 600m west in 25 seconds, what is its velocity?
Elena L [17]

v =  \frac{ \:the covered distance}{time} \\

v =  \frac{600}{25} =  \frac{6 \times 100}{25} = 6 \times 4 = 24 \:  \\

v = 24 \:  \frac{m}{s} \\

_________________________________

If west means the west of the axis x the velocity equal :

- 24 \:  \frac{m}{s} \\
