1.) A ball with mass 5.0 kg is launched upwards towards the east into the air with a speed of 15. m/s at an angle of 30 degrees to the ground. Note: For this question the motion is fully three-dimensional. Orient your axes so that the positive y-axis points north, the positive X-axis points east, and the positive z-axis points upwards (towards the sky. 1A.) If a gusting...
