A 55-kg soccer player jumps vertically upwards and heads the 0.45-kg ball as it is descending vertically with a speed of 23 m/s. (a) If the player was moving upward with a speed of 4.0 m/s just before impact, what will be the speed of the ball immediately after the collision if the ball rebounds vertically upwards and the collision is elastic?(b) If the ball is in contact with the player's head for 23 ms, what is the average acceleration of the ball? (Note that the force of gravity may be ignored during the brief collision time.)

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...
