Chapter 2: Problem 8

In a game against the White Sox, baseball pitcher Nolan Ryan threw a pitch measured at \(45.1 \mathrm{m} / \mathrm{s} .\) If it was \(18.4 \mathrm{m}\) from Nolan's position on the pitcher's mound to home plate, how long did it take the ball to get to the batter waiting at home plate? Treat the ball's velocity as constant and ignore any gravitational effects.

Short Answer

Expert verified
Answer: Approximately 0.408 seconds.

Step by step solution

01

Write down the given information

We are given the following information: - Velocity of the baseball (\(v\)): \(45.1 \mathrm{m/s}\) - Distance between the pitcher's mound and home plate (\(d\)): \(18.4 \mathrm{m}\) Our goal is to find the time it takes (\(t\)) for the ball to travel from the pitcher's mound to home plate.
02

Use the formula for constant velocity

We will use the formula for constant velocity, which is: \(distance = velocity \times time\) In our case, the distance (\(d\)) is \(18.4 \mathrm{m}\) and the velocity (\(v\)) is \(45.1 \mathrm{m/s}\). So, we can rewrite the formula as: \(18.4 \mathrm{m} = 45.1 \mathrm{m/s} \times t\)
03

Solve for time

To solve for the time (\(t\)), we will divide both sides of the equation by the velocity: \(t = \frac{18.4 \mathrm{m}}{45.1 \mathrm{m/s}}\) By calculating the fraction, we get: \(t = 0.408 \mathrm{s}\)
04

State the final answer

The time it takes for the baseball to travel from the pitcher's mound to home plate is approximately \(0.408 \mathrm{s}\).

A motor scooter travels east at a speed of \(12 \mathrm{m} / \mathrm{s}\). The driver then reverses direction and heads west at \(15 \mathrm{m} / \mathrm{s}\) What is the change in velocity of the scooter? Give magnitude and direction.
A chipmunk, trying to cross a road, first moves \(80 \mathrm{cm}\) to the right, then \(30 \mathrm{cm}\) to the left, then \(90 \mathrm{cm}\) to the right, and finally \(310 \mathrm{cm}\) to the left. (a) What is the chipmunk's total displacement? (b) If the elapsed time was \(18 \mathrm{s},\) what was the chipmunk's average speed? (c) What was its average velocity?
In the problems, please assume the free-fall acceleration $g=9.80 \mathrm{m} / \mathrm{s}^{2}$ unless a more precise value is given in the problem statement. Ignore air resistance. A stone is thrown vertically downward from the roof of a building. It passes a window \(16.0 \mathrm{m}\) below the roof with a speed of $25.0 \mathrm{m} / \mathrm{s} .\( It lands on the ground \)3.00 \mathrm{s}$ after it was thrown. What was (a) the initial velocity of the stone and (b) how tall is the building?
A ball thrown by a pitcher on a women's softball team is timed at 65.0 mph. The distance from the pitching rubber to home plate is \(43.0 \mathrm{ft}\). In major league baseball the corresponding distance is \(60.5 \mathrm{ft}\). If the batter in the softball game and the batter in the baseball game are to have equal times to react to the pitch, with what speed must the baseball be thrown? Assume the ball travels with a constant velocity. [Hint: There is no need to convert units; set up a ratio.]
please assume the free-fall acceleration \(g=9.80 \mathrm{m} / \mathrm{s}^{2}\) unless a more precise value is given in the problem statement. Ignore air resistance. A penny is dropped from the observation deck of the Empire State building (369 m above ground). With what velocity does it strike the ground?
