Tanjiro is driving a 1500 kg truck while pulling a trailer. His acceleration is 1 m/s2. Nezuko is inside the trailer which has mass of 2000 kg. Determine the force the truck is applying on the trailer. Ignore friction. Note: Answer should be in whole number. No unit is required for this question.
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?
