Answer:10
Explanation:because 5x10=50 and if you take away the decimal it is wrote "50"
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)
=> 
= >
I beleve the answer is D).
Answer:
a) The work done by a nonconservative force depends on the path taken. True.
c) A potential energy function can be specified for a conservative force. True
d) A conservative force permits a two-way conversion between kinetic and potential energies. True
Explanation:
Non-conservative forces dissipate. For example, friction or air resistance or drag.
A conservative force's property is that the work done in moving a particle does not depend on the path it has taken. For example, stored energy or potential energy. It permits two-way conversion between kinetic energy and potential energy. For example if a car goes up a hill, it converted kinetic energy in to potential energy. and if the car goes down the hill without hitting the gas pedal, it will roll down converting the potential energy in to kinetic energy.
b) A nonconservative force permits a two-way conversion between kinetic and potential energies. False
e) A potential energy function can be specified for a nonconservative force. False
f) The work done by a conservative force depends on the path taken. False
d, be clear about your response
a, possible dependency
d, refusal skills
