The speed is constant since there is no opposite force facing the car
That’s my best guest hope it helps !! :)
Im not exactly sure but I think the answer is techtonic plates collide
It’s c, the toy car changes direction
From someone who has taken physics this is, True
Yes. Think of block sitting on top of a bigger block. If the bottom block moves, it will drag the top block with it. Since the force of friction on the small block and its displacement are in the same direction, the "work" is positive. The static friction is a passive force, It is not a source of energy; it transmits the force placed on the bottom block. (And the "work" done by the friction on the bottom block is exactly the negative of the work done on the top block.)
