About this document

Class 9 Motion Equations Explained by Vishva Opanayaka is a document available to read on EtoBox.

The document discusses the calculation of various quantities related to the motion of a ball fired at an angle and arrows shot from a bow. It first calculates the time for the ball to travel 30 meters as 1.2 seconds. It then finds the westward component of velocity as 9.6 m/s and the distance traveled west as 5.76 meters. Using trigonometry, it determines the final velocity of the ball as 26.8 m/s at an angle of 21 degrees west. It also calculates the initial vertical velocity of arrows from a bow as abo
