An old building is being demolished by swinging a heavy metal ball from a crane. Suppose that such a 115kg ball swings from a 20

-m-long wire at speed 12m/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?

Dominik [7]

Answer:

14.8m

Explanation:

Given parameters:

Initial speed  = 17m/s

Unknown:

Maximum height  = ?

Solution:

At the maximum height, the final speed will be 0m/s;

 We use of the kinematics equation to solve this problem.

     V²   = U²   - 2gH

V is the final velocity

U is the initial velocity

g is the acceleration due to gravity

H is the height

         0²   = 17²  -  (2  x 9.8 x h )

          0 = 289  - (9.6h)

         -289  = -19.6h

            h  = 14.8m

A wave amplitude 0.36m interferes with a second wave of amplitude 0.22m traveling in the same direction. What is the largest res
DerKrebs [107]
The largest resultant amplitude would be that created by constructive interference, basically when the two waves are of the same phase, so it would be 0.36m+0.22m= 0.58 m.
