θSoccer “kicking” machineAssume that the foot hits the soccer ball in position 2 as shown, where the spring is unstretched. soccer ball is rolling towards the “foot” with a speed of 2 m/s at an angle θ= 30oas shown. The impact occurs when the foot is at position 2. If the friction coefficient during rolling is μk0.1, find the necessary spring coefficient to make the ball roll 30 meters. Also determine the direction the ball will be kicked. . A =
What type of problem?•Blocks A and B have masses of 11kg and 5 kg, respectively. They are both released from rest at h=2 m. If it is a frictionless, massless pulley, what is the velocity when A hits the ground?
What coordinates would you use?
What coordinates would you use?A package is dropped on the setup shown. What is the spring constant necessary to bring it to rest in 1.3 meters?Kinematics or Kinetics?
