What angle is formed when the time reaches 6 o'clock?
180 degrees
How many points are needed to determine a trajectory line?
To determine a trajectory line, only two points are needed. These two points can be used to calculate the slope, which represents the direction and angle of the trajectory. Additional points can be used to further refine the trajectory line and estimate its accuracy.
When does an acute angle cease to be acute?
When it is larger than 90 degrees.When it reaches 90
How do you calculate the initial angle of a parabolic trajectory given the complete formula for the parabola?
the ofrmula is x=-b/ab... trust me in in 8th grade taking a 11th grade course!!
Does a 10lb catapult launch further than a 3lb one?
Usually yes...but it depends on the angle of trajectory, weight and aerodynamics of the thing being catapulted, the length of the "arm" of the catapult, and the amount of force that the catapult is set to hurl the object. Example: a feather on the 10lb catapult which is set at a high trajectory and a low force will go almost nowhere while a stone from a 3 pound catapult will go much farther if it is set on a perfect trajectory and maximum force.
