Mighty Casey hits two baseballs out of the park. The path of the first baseball can be described by the displacement (distance and direction) vector / purple{/vec{b_1}} = 100 / hat i + 10/hat j

start color #9d38bd, b, start subscript, 1, end subscript, with, vector, on top, end color #9d38bd, equals, 100, i, with, hat, on top, plus, 10, j, with, hat, on top. The path of the second baseball can be described by the displacement vector / blue{/vec{b_2}} = 90/hat i + (-20) / hat j
