Afather fashions a swing for his children out of a long rope that he fastens to the limb of a tall tree. as one of the children swings from this rope that is 6.10 m long, his tangential speed at the bottom of the swing is 9.70 m/s. (a) what is the centripetal acceleration of the child at the bottom of the swing? m/s2 (b) what provides the centripetal force that keeps the child moving in an arc? 0 the weight of the child o the tension in the rope o the height of the tree o gravitational acceleration
