Constant velocity in a positive direction
Web1. Velocity is the slope of position vs. time. If that slope is not changing, the velocity is constant. If the slope is negative and not changing, the velocity is a negative constant. Acceleration is slope of velocity vs time. 2. Yes, … WebA person pushes a 16.0-kg shopping cart at a constant velocity for a distance of 22.0 m. She pushes it in the direction 30.0° below the horizontal. A 48.0-N frictional force opposes the motion of the cart. (a) Draw the free-body diagram showing the forces that act on the cart. (b) What is the magnitude of the force that the shopper exerts?
