At an instant when a soccer ball is in contact with the foot of the player kicking it, the horizontal or x component of the ball's acceleration is 920 m/s2 and the vertical or y component of its acceleration is 910 m/s2. The ball's mass is 0.43 kg. What is the magnitude of the net force acting on the soccer ball at this instant?

10.7 A soccer player deflects a soccer ball by kicking it. Initially the soccer ball (mass 0.40 kg) is moving horizontally to the left witha speed of 20.0 m/s. The kick causes it to have an initial, post-kick velocity of 30.0 m/s with an angle of 45 upward and to the right. If the time that the player's foot is in contact with the soccer ball is 0.010 seconds find: A. The impulse of the net force The average net...

17) A soccer player is redirecting the ball with her foot. At the instant before it is contacted by the player's foot, the bal is moving at a velocity (VB) of 6 m/s in the direction shown in the overhead view on the left below i) (1pt) The player wants to speed up the ball's "forward" motion in its current direction while causing its motion to turn to the left of its current direction. If she is to do so,...

A soccer ball with mass 0.470 kg is initially moving with speed 2.30 m/s . A soccer player kicks the ball, exerting a constant force of magnitude 39.0 Nin the same direction as the ball's motion. Over what distance must the player's foot be in contact with the ball to increase the ball's speed to 6.00 m/s?
