Answer:

The correct option is 'D': Equal and opposite force.

Explanation:

We know from Newton's third law of motion

"For every action there exists an equal and opposite reaction".

The statement is further explained as

If there exists a force from Body 1 to Body 2 then Body 2 must also exert an equal and opposite force on the Body 1.

In simple terms we can say that the action and the reaction forces exist in pairs and are always present if any one among them is present.

a freight train travels at v=60(1-e^-t) ft/s, where t is the elapsed time in seconds. Determine the distance traeled in tree sec
lesantik [10]

Answer

given,

v = 60(1-e^{-t})\ ft/s

t = 3 s

we know,

v = \dfrac{dx}{dt}

a = \dfrac{dv}{dt}

position of the particle

dx = v dt

integrating both side

\int dx =\int 60(1-e^{-t}) dt

x = 60 t + 60 e^{-t}

Position of the particle at t= 3 s

x = 60\times 3+ 60 e^{-3}

 x = 182.98 ft

Distance traveled by the particle in 3 s is equal to 182.98 ft

now, particle’s acceleration

a = \dfrac{dv}{dt}

a = \dfrac{d}{dt}60(1-e^{-t})

  a = 60 e^{-t}

at t= 3 s

  a = 60 e^{-3}

    a = 2.98 ft/s²

acceleration of the particle is equal to 2.98 ft/s²
