Dear student,

Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

Thanks for asking ..m=6.7kg ,l=2.51m, 0=39.7° lso (l-lloso) To Dyo using conservation of energy. layalam mg (2-1680) - Lyhy? V=J2gell-copo =) V=1

    A pendulum consists of a small object hanging from the ceiling at the end of a string of negligible mass. The string has a length of 0.71 m. With the string hanging vertically, the object is given an initial velocity of 1.6 m/s parallel to the ground and swings upward in a circular arc. Eventually, the object comes to a momentary halt at a point where the string makes an angle θ with its initial vertical orientation and then swings...
