During a demonstration of the gravitational force on falling objects to her class, Sarah drops an 11 lb. bowling ball from the top of the science building. Determine distance the ball has traveled after falling for 1.0 second, ignoring air resistance and given the gravitational acceleration of 9.8 m/sec2.
A) 4.9 m
B) 11 m
C) 20 m
D) 32 m

 C) 20 m 
 D) 32 m

BenLindquist · Answer

Your answer would be c because: Mass = 11 lb. convert to kg = 5 kg
Gravity = 9.8 m/s2
Time (final) = 3.0 s

v= at
v =  9.8m/s2(3.0s) 
= 29.4 m/s
