Question

A blueberry and an olive fall off of a kitchen counter and start rolling on the floor. The masses and speeds of the fruits are in the table below. Fruit & Mass (g) & Speed ((mathrm(m))/(mathrm(s))) blueberry & 1 & 3 olive & 3 & 1 How do the kinetic energies of the two fruits compare? Choose 1 answer: (A) The blueberry has more kinetic energy. (B) The olive has more kinetic energy. (C) Both fruits have the same kinetic energy.

Answer 1

### A. The blueberry has more kinetic energy.

Answer 2

## Step 1: Understand the problem### We need to compare the kinetic energies of two fruits: a blueberry and an olive. Kinetic energy is given by the formula:

## Step 2: Calculate the kinetic energy of the blueberry### The mass of the blueberry is

(which we will convert to

for SI units), and its speed is

:

## Step 3: Calculate the kinetic energy of the olive### The mass of the olive is

(which converts to

), and its speed is

:

## Step 4: Compare the kinetic energies### The blueberry has a kinetic energy of

, while the olive has a kinetic energy of

. Thus, the blueberry has more kinetic energy.
