The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
What is Impulse?
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
