Answer:
The value is 
Explanation:
From the question we are told that
The velocity of the each of the three cars is 
The velocity of the fourth car is 
The initial velocity of the fifth car 
Generally from the law of momentum conservation we have that
![m_1 u_1 + m_2 u_2 + m_3 u_3 +m_4u_4 + m_5u_5 = [m_1 + m_2 + m_3 +m_4+ m_5]v](https://tex.z-dn.net/?f=m_1%20u_1%20%2B%20m_2%20u_2%20%2B%20m_3%20u_3%20%2Bm_4u_4%20%2B%20m_5u_5%20%3D%20%20%5Bm_1%20%20%20%2B%20m_2%20%2B%20m_3%20%2Bm_4%2B%20m_5%5Dv)
Given that the cars are identical then their mass will be the same
i.e
=> ![[u_1 + u_2 + u_3 +u_4 + u_5]m = 5mv](https://tex.z-dn.net/?f=%5Bu_1%20%2B%20u_2%20%2B%20%20u_3%20%2Bu_4%20%2B%20u_5%5Dm%20%3D%20%205mv)
=>

Hurricanes and tropical storms can also spawn tornadoes and microbursts, create storm surges ... If you are unable to evacuate, go to your wind-safe room.

If you are given time and distance, you can determine power if you know
force. watts. energy. joules.
Answer is joules.
Power is defined as the rate of
doing work. Hence power = work / time then you obtain watts. Work is the
product of force and displacement (distance). Hence in formula, w = F x s. In
which the S.I unit of work is joule in the product. This is what you have to
obtain in order to calculate for power.
