You are watching an archery tournament when you start wondering how fast an arrow is shot from the bow. Remembering your physics, you ask one of the archers to shoot an arrow parallel to the ground. Unfortunately the archer stands on an elevated platform of unknown height. However, you find the arrow stuck in the ground 56.0 m away, making a 2.00 ∘ angle with the ground. How fast was the arrow shot?

A ball swings counterclockwise in a vertical circle at the end of a rope 1.50 m long. When the ball is 36.9° past the lowest point on its way up, its resultant acceleration is a = (-22.5i + 20.2j) m/s2 , where i is the unit vector along the horizontal direction (you can treat it as pointing to the right), and j is the unit vector along the vertical direction (you can treat it as pointing upward). For that instant, (i) determine the magnitude of its centripetal acceleration in m/s2 (ii) determine the speed of the ball in in m/s (iii) determine the velocity of the ball in m/s, i and j.

Problem: A person who is 1.3 m tall throws a ball with a speed of 19m/s at an angle of 17 degrees above horizontal. One part of the problem asks me to find the x and y components of the ball's velocity before it hits the ground. I have tried using the vy^2 = voy^2 + 2ah for the y-component: vy^2 = (5.56)^2 + (2)(10)(1.3) = 7.54 and my x-component is just (19)(cos(17))= 18.17 m/s, but it is saying this is not the right answer. What am I doing wrong?

Fluid Mechanics: The English perfected the longbow as a weapon after the Medieval period. In the hands of a skilled archer, the longbow was reputed to be accurate at ranges to 100 m or more. If the maximum altitude of an arrow is less than h = 10 m while traveling to a target 100 m away from the archer, and neglecting air resistance, estimate the speed and angle at which the arrow must leave the bow. Plot the required release speed and angle as a function of height h
