You are driving a car with a speed of 100mph, you applied brakes to avoid hitting a deer. how many calories of heat are produced in the stopping process if the car mass is 1000 kg?

Respuesta :

The correct answer is 238820.22 calorie.

We need to understand the concept of heat, the SI unit of heat, and what a calorie is in order to answer this problem. Most of us use the word "heat" to describe anything that feels warm, but according to science, heat is the movement of energy from a warm object to a cooler one. Based on this, heat is divided into two categories: hot and cold. Icebergs, volcanoes, and even human bodies contain heat energy.

v = 100 mph

v = 100 mph = 44.704 m/s

Energy = 1/2m(v_f^2- v^2)

The heat generated = 1/2 × 1000× 44.704^2

H= 999223.828 J

H= 238820.22 Calorie
