    What Happens to a Pendulum's Height at a 90-Degree Angle?

    [b]1.2. If a ball and string pendulum is pulled and lifted to a height = 10 cm and the length of the string is 1 m what will be the value of h when the string makes an angle of 90 degree with the vertical? Please ignore the 0.5 m it should be a h = 10 cm or 0.1 m the diagram is to provide a...

    How Do You Calculate the Third Force in a System of Connected Masses?

    1.I am stuck on this problem can anyone help me? A 20-kg object is subjected to three forces which produce an acceleration a = -8 m.s-2 i + 6.0 m.s-2 j on the object. Two of the forces are: F1 = 3.0 N i + 16.0 N j F2 = -12.0 N i+ 8.0 N j Find the third force. 2. Homework Equations...
