ΔT= 81°C was the increase in temperature.

<h3>steps</h3>

As evidenced by energy conservation

To increase its temperature, all of its kinetic energy will be converted to thermal energy.

$\frac{1}{2}mv ^{2} = ms$ ΔT

then divide both sides by the object's mass.

$\frac{1}{2} v^{2} =s$ ΔT

therefore, a temperature shift is described as

ΔT= $V^{2} /2s$

ΔT= $25^{2}$ / 2 x 387

ΔT= 81°C

ΔT= 81°C was the increase in temperature.
