Lucy boards a crowded bus as it sits in the station. there are no available seats, so lucy stands in the center aisle next to a support pole. as the bus starts moving forward and picks up speed, lucy holds the pole tightly to avoid falling over backward. while the bus is speeding up, what is the direction of the total force (if any) on lucy? a. is it forward b. baclwards c. the total force is zero?

The acceleration of the bus is forward, and said acceleration is transmitted directly to Lucy, so the direction of the Force (We gather that force is equal to mass by acceleration) will be forward as well. Lucy's immediate action will be to fall back because she tries to resist this movement.

Therefore the correct answer is A.

dang that balls went far

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
