A soccer ball is kicked from ground level across a level soccer field with initial velocity vector v0 = 5 m/s at θ = 28° above horizontal. The soccer ball feels wind resistance which causes it to slow horizontally with constant acceleration magnitude an x = 0.66 m/s2, while leaving its vertical motion unchanged. Assume any other air resistance is negligible. Choose the positive direction of x from initial point towards final point of flight. Use a Cartesian coordinate system with the origin at the ball's initial position.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p

If an athlete runs once around a track, back to the starting line, her average velocity is zero. true or false?
