    Findi angular range given initial velocity and distance

    Also, the minimum angle should be at the point where the displacement vector of the ball is (50, 3.44, 0), since any more and the angle could be lower, and any less y displacement it wouldn't go over the post.. Bumping again!

    Why does only constant speed accelerate and not constant velocity?

    scalar means only the magnitude, or size is important. So in the case of speed and velocity, the 'magnitudes' of their motion is how fast they are going

    Why does only constant speed accelerate and not constant velocity?

    Since speed it a scalar quantity it only refers to how fast an object is moving. Velocity is a vector, meaning that its speed AND direction are important. Acceleration is also a vector quantity, so if an object's movement either changes direction, or goes faster, there is aceleration. If an...

    Findi angular range given initial velocity and distance

    Homework Statement A kicker is attempting a field goal from 50 m from the goal posts, which are 3.44 m high. He can kick the ball with initial speeds of 25 m/s. Ignoring air resistance, within what angular range must he kick the ball to score? Homework Equations Pf = Pi + Fnet*t And any...
