Free moving particle with mass m (three degrees of freedom); (b) particle with mass m moving in the gravitational field at the surface of the earth: vertical motion of a falling object (one degree of freedom); (c) particle with mass m moving in the gravitational field at the surface of the earth: motion of a projectile (two degrees of freedom). 3. derive euler-lagrange equations (ele) for the three mechanical systems (a, b, and c) in the previous problem 2.

Need in all of themmm only answer if you know plsssss

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
