Problem 81PE
Suppose you hit a steel nail with a 0.500-kg hammer, initially moving at 15.0 m/s and brought to rest in 2.80 mm. (a) What average force is exerted on the nail? (b) How much is the nail compressed if it is 2.50 mm in diameter and 6.00-cm long? (c) What pressure is created on the 1.00-mmdiameter tip of the nail?
ANSWER:
Step 1 of 9
a.)
The average force exerted on the nail can be computed by equating the kinetic of energy of the hammer to work done in bringing the nail to rest at 2.8 mm
