KE= 1/2MV^2 - equation
KE= 1/2 (2 kg)(15 m/s)^2 - plug it to the equation
KE= (1 kg)(225 m/s) - multiply
KE= 225 J - Answer (letter D)
Hope this helps
To neutralize gastric juices in your stomach antacids contain basic
chemicals. The acid in your stomach has a lower pH value. To neutralize this
and reach a pH of 7, the antacid must contain a base.
Work = Force * Displacement.
If the Work is the same, and the Force is increased, from the formula above it means the displacement would have to be reduced.
So the displacement (a distance in a specified direction) would be reduced.
