In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweet headed goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming the positive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of the force she applied to the ball? Note- you can ignore the weight of the ball.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
