Kinematics in Two Dimension Practice Problems: Constant Velocity

Today we are solving a two dimensions problem for Kinematics of particles with a constant velocity. please reach out to me if you have any questions about anything in the video and I will be happy to help you. The quarterback 𝑄 throws the football when the receiver 𝑅 is in the position shown. The receiver’s velocity is constant at 10 𝑦𝑑/𝑠𝑒𝑐, and he catches passes when the ball is 6 𝑓𝑡 above the ground. If the quarterback desires the receiver to catch the ball 2.5 𝑠𝑒𝑐 after the launch instant shown, determine the initial speed 𝑣" and angle 𝜃 required
