Question

A hammer is dropped and it falls for 5 seconds before hitting the ground. Determine how far it falls, assuming an acceleration due to gravity of − 9.8 m/s 2 and no wind resistance.

Answer 1

Answer:

h=122.5m

Step-by-step explanation:

$h=v_{o}*t+\frac{1}{2}gt^{2}\\h=0*5+\frac{1}{2}(-9.8\frac{m}{s^{2}})*(5s)^{2}\\h=-4.9\frac{m}{s^{2}}*25s^{2}\\h=122.5m$
