Question

The fiqure below shows a bead sliding without friction along a curved wire in a vertical plane The bead slides starting from rest at position C on the frictionless wire. The direction of the gravitational field is in the -y direction (toward the bottom of the page) Equal to The acceleration in the x-direction at D is True True True The velocity at H equals the velocity at A. Equal to The speed at H is the speed at A. Greater than The speed at D is.. the speed at H zero. The acceleration at H is zero. The acceleration in the y-direction at D is... zero. Submit Answer Incorrect. Tries 4/6 Previous Tries

Explanation / Answer

part a ) equal to zero , because it is not moving in x direction

part b ) False , gravitational acceleration always pushing beard towards down

part c ) False

part d ) false , because velocity have direction both have different direction

part e ) equal , speed has only magnitude not direction

part f ) greater than , kinetic energy converts into potential energy
