It took 0.45 s for a fastball to reach the batter. If the pitcher is 18 m away from the batter, how fast was the fastball pitch?
A. 0.025 m/s
B. 8.1 m/s
C. 18 m/s
D. 40 m/s
I say it is D. To let you know; this is not a test, it's only a practise quiz I'm doing.
You are lucky, d is the answer.
To find the speed of the fastball pitch, we can divide the distance traveled by the time taken. The distance traveled is the distance between the pitcher and the batter, which is 18 m. The time taken is given as 0.45 s.
Speed = Distance / Time
Speed = 18 m / 0.45 s
Speed = 40 m/s
Therefore, your answer of D) 40 m/s is correct. Well done!
