Question

A 9 kg box is moving at a constant speed of 6 m/s to the right of a table. It experiences a leftward force of 13 N and an unknown rightward force. A. Draw a force diagram describing this situation. Please label all forces. B. Determine the magnitude of the unknown rightward force. Explain how you know.

Answer 1

Here as we can see the figure the object must have to move with constant speed

So here net force on the object must be zero

so we can say

`F_(left) = F_(right)`

so here we will have

`F = 13 N`

so there will be 13 N force towards right on this box
