Please answer all parts :), I think I have the answer to part one, I just cant figure out the rest 1. A magnet of mass 4.44 kg is suspended from the ceiling by a cord as shown. A large magnet is somewhere off to the right, pulling on the small hanging magnet with a constant force of F = 65.3 N. At what angle theta ?with respect to the vertical does the magnet hang? 2. Consider the same situation as in the previous problem. This time the magnet has mass 6.75 kg and the force pulling the magnet to the right has magnitude 56.1 N. What is the magnitude of the tension force in the cord? 3. Same situation as in the previous two problems this time the magnet s mass is 4.56 kg and the magnetic force pulling it to the right is 117.2 N.

Clarification: 1 h / 2 = 30 minutos The whole statement is in the picture. A block of mass ?1 = 250? is at rest on a plane that makes an angle ? = 30 ° about the horizontal. The coefficient of kinetic friction between the block and the plane is ?? = 0.100. This block is attached to a second block of mass ?2 = 200? that hangs freely from a rope that passes from a pulley without friction and with negligible mass. When the second block has fallen 30 cm, its speed is; a). 83 cm / s b). 160 cm / s If the rope breaks, after having traveled h / 2, calculate: The acceleration of each block. The time block 2 reaches the ground. The speed of block 2, an instant before it hits the ground and of block 1 when it reaches the end of the ramp.
