The work done onto the car is 506,250 J
The work done on a system implies an increase in the internal energy of the system as a result of some forces acting on the system from the outside.
From the parameters given:
- The mass of the car = 1500 kg
- The initial speed = 30 m/s
- The final speed = 15 m/s
The work done onto the car refers to the change in the kinetic energy (i.e. ΔK.E)
= 506,250 J
Therefore, we can conclude that the work done on the car is 506,250 J

I have no idea what the exact answer is, so sorry in advance but ik it’s definitely less than four, but greater than three.. lol hope that helps some
Answer:
27%
Explanation:
15.999 divided by 58.32 = .27433128
Move the decimal place over 2 places.
27%
Answer:
block 2 or 4
because of the distribution of weight and force being applied to the object
Explanation:
In Europe the standard voltage in homes is 220 V instead of the 120 V used in the United States.
100-W European bulb would be intended for use with a 220-V potential difference.
(a) If V = 220 V and P = 100 W
Power :
If you bring a "100-W" European bulb home to the untied States, what should be its US power rating. So,
or
P = 29.8 watts
(b) Let I is the current will the 100-W European bulb draw in normal use in the United States. So,
Hence, this is the required solution.
