Conversions of a thrown basebal

    1. The problem statement, all variables and given/known data

    a good baseball pitcher can throw a baseball toward home plate at 85 mi/h with a spin of 1800 rev/min. how many revolutions does the baseball make on its way to home plate? for simplicity, assume that the 60 ft path is a straight line.

    2. Relevant equations

    3. The attempt at a solution

    First, we need to convert the unit from miles to feet. Since 1 mile = 5280 feet, 85 mi/h becomes 7480 ft/min.
    And we need to do with 1800 rev/min. what should I do with it?

    Re: conversion

    I got it.
    1800 * 60 = 108000.
    108000 / 7480 = 14.44
