A horse pulls on a crate with a 1,000 N force, causing it to move at constant velocity. What is the acceleration of the cart? A 44-kg child steps onto a scale. What is the magnitude of the force that the scale exerts on the child

Question

A horse pulls on a crate with a 1,000 N force, causing it to move at constant velocity.  What is the acceleration of the cart? A 44-kg child steps onto a scale.  What is the magnitude of the force that the scale exerts on the child

drwls · Answer

These are two different questions (1) Constant velocity means zero acceleration. (2) Weight = M*g = 44*9.8 Newtons It is the same force that the child exerts on the scale.
