Question (1250001) - High Point University
... A 0.4-kg soccer ball is kicked from a location < 8, 0, −8 > m (on the ground) with initial velocity < −9, 14, −4 > m/s. The ball's speed is low enough that air resistance is negligible. Therefore, you can assume that the net force is constant. (Note: the +y direction is de ned to be perpendicular to ...

... There are many misconceptions about Newton’s First Law. Read: "How many ways can you state Newton's First Law?" and "Thoughts on force..."to try and understand how it fits to many situations. Newton’s first law states that an object will remain stationary or continue at a constant velocity unless ac ...
