Isn't this Physics?

yea are you able to help me? @Jesstho.-.

swissgirl · Answer

acceleration = dv/dt
or the rate of change of v
the speed was changing positively so acceleration was positive
force = m*a
         =mass is positive and acc is positive so force is positive

swissgirl · Answer

if the backward force is greater than you would be decelerating (slowing down)

swissgirl · Answer

There is a net force on the car that is pushing the car forward making it speed up.
