25 POINTS PLEASE HELP ME ASAP A cart is moving on a flat surface that has negligible friction. What will happen to its speed?
The cart's speed will increase

The cart's speed will stay constant

The cart's speed will decrease

The cart's speed will initially increase, and then decrease

Which statement about the speed of a chair is correct?
After I push a chair on a frictionless surface, the chair will speed up forever because there is no friction

After I push a chair on a frictionless surface, the chair will move at a constant speed for a while, but eventually slow down because the energy will run out.

After I push a chair on a frictionless surface, the chair will move at a constant speed because there is no longer an energy transfer

After I push a chair on a frictionless surface, the chair will stop because there is no longer a transfer of energy from the hand to make it move
