A tennis ball is thrown upward at an angle from point A. It follows a parabolic trajectory and hits the ground at point D. At the instant shown, the ball is at pointB. Point C represents the highest position of the ball above the ground.
While in flight, how do the x and y components of the velocity vector of the ball compare at the points A and D?
A) The velocity components are non-zero at A and are zero m/s at D.
B) The velocity components are the same in magnitude and direction at both points.
C) The velocity components have the same magnitudes at both points, but the directions of the y components are reversed.
D) The velocity components have the same magnitudes at both points, but their directions are reversed.
E) The velocity components have the same magnitudes at both points, but the directions of the x components are reversed.

A ball is launched from the ground at an angle of 65∘ above the horizontal with a velocity of 22m/s. The ball hits the ground some distance away at a given speed, and bounces back up. When it does so the amplitude of both the x and y components of its velocity are half what they were. This repeats with the ball losing half of it’s speed on each bounce. a) Sketch the problem. [2 points b) Write the equation...

2. A baseball thrown from the outfield, a golf ball, or a thrown football, all will follow a trajectory (path) that has horizontal as well as vertical displacement components. If we neglect the air friction on the ball, the path will be a perfect parabolic trajectory. The equations for the displacement of the ball are: Take gravity g as 9.81 meters per second, and the initial velocity, Vo, equal to 35 meters/second. Use Excel to show the ball trajectory for...
