Demolition An old building is being demolished by swinging a heavy metal ball from a crane. Suppose that such a 100- kg ball swings from a 20-m-long wire at speed 16 m/s as the wire passes the vertical orientation. (a) What tension force must the wire be able to withstand in order not to break? (b) Assume the ball stops after sinking 1.5 m into the wall. What was the average force that the ball exerted on the wall? Indicate any assumptions you made for each part of the problem.
