physics question?

At the low point in its swing, a pendulum bob with a mass of 0.6 kg has a velocity of 15 m/s.

(a) What is its kinetic energy at the low point?

(b) Ignoring air resistance, how high will the bob swing above the low point before reversing direction?

    a) KE = 1/2 x M x V^2

    put the numbers and you'll get the answer

    b) It will gradually decrease in speed, and KE will be covered to Potential Energy. And then it will swing back, due to the force of gravity

    KE = 1/2 mv²

    KE = PE
