Leanne is riding a bike. The forward force from her pedalling is 18N. There is a backward force of 6N from friction and a backward force of 12N from air resistance. Does the speed of the bike increase, decrease or not change?

    the net force acting on the bike is=

    18 - 6 - 12 = 0 N.

    Since the net force acting on the bike is zero, the bike is moving with constant velocity. Therefore, the speed of the bike does not change.

    The speed of the bike does not change because the total force that is pushing her back is 18 Newtons and her forwards force is 18 newtons is her force is balanced and therefore will not change
