\text{elastic potential} \quad \text{gravitational potential} \quad \text{kinetic} \quad \text{chemical}

As the coconut falls towards the ground, there is a decrease in its __________ energy.

As the coconut falls towards the ground, there is an increase in its __________ energy.

[2]

Write down the equation which links kinetic energy ( $E_k$ ), mass ( $m$ ), and speed ( $v$ ).

[1]

At the instant just before the coconut hits the ground, the kinetic energy of the coconut is $J48\text{ J}$ .

The speed of the coconut is $m/s8.0\text{ m/s}$ .

Calculate the mass of the coconut.

[3]

When the coconut hits the ground, most of its kinetic energy is transferred to the ground.

How does this affect the thermal energy of the ground?

The thermal energy decreases.
The thermal energy stays the same.
The thermal energy increases.
