The linear momentum of a 100.0 kg object moving around a 30.0 m circle at a constant speed of 2.20 m/s is
A) 0.0 N
B) 220 N
C) 242 N
D) 6600 N

Linear momentum ($p$) is defined as the product of mass ($m$) and velocity ($v$), given by the formula $p = mv$. For the object in question, $m = 100.0\,kg$ and $v = 2.20\,m/s$, so $p = 100.0\,kg \times 2.20\,m/s = 220\,kg\cdot m/s$, which is equivalent to 220 N·s, not N, indicating a mistake in the units provided in the options.
