This is a projectile motion question.
A ball with a mass of .4 kg, initially at rest is kicked directly toward a 3 meter fence from a point 20 meters away. The initial velocity is 17 m/s at an angle of 35 degrees. The ball is hit by nothing and there is no wind resistance, but gravity is still its normal acceleration of -9.8 m/s. How long does it take to reach the plane of the fence,how far above the top of the fence does it pass (diameter disregarded) and what is the vertical component of the velocity when it crosses the plane.
