A skateboarder shoots off a ramp by a velocity of 6.8 m/s, directed at an angle of 54° above the horizontal. The end of the ramp is 1.1 m above the ground. Let the x axis be parallel to the ground, they direction be vertically upward, and take as the origin the point on the ground directly below the top of the ramp.
1. Wasn’t sure how to figure out the skateboarder’s highest point?
2. How can i tell where the highest point reached is on the x axis or horizontally?
