APPHMC-YSD$SH

A toddler drops a large chunk of oatmeal straight down from a height of $1.0m$. The oatmeal lands on his sister's $200g$ toy truck as it rolls by at $1.5\text{ }m/s$. The speed of the truck is $1.4 m/s$ after the oatmeal lands on it and sticks.

What is the mass of the chunk of oatmeal $m_2$?

A

$m_2 = 0.014\text{ }g$

B

$m_2 = 3.7\text{ }g$

C

$m_2 = 7.7\text{ }g$

D

$m_2 = 13.3\text{ }g$

E

$m_2 = 14.3\text{ }g$
