Chapter 9: 9.Q. 13 (page 227)

The driver of a car traveling at 60 mph slams on the brakes, and the car skids to a halt. What happened to the kinetic energy the car had just before stopping?

Short Answer

Expert verified

The Kinetic energy gets converted to heat energy (due to friction) and Sound energy .

Step by step solution

01

Given information

The driver of a car traveling at 60 mph slams on the brakes, and the car skids to a halt

02

Explanation

When a break is applied on a moving car the kinetic energy decreases.

From the law of conservation of energy, we know the energy can't be destroyed. So the kinetic energy gets converted into another form energy.

In this case, the kinetic energy gets converted into heat energy and sound energy (due to friction) between surface and car.

Evaluate the dot product $\vec{A} \cdot \vec{B}$ if

a. $\vec{A} = 4 \hat{i} - 2 \hat{j}$ and $\vec{B} = - 2 \hat{i} - 3 \hat{j}$ .

b. $\vec{A} = - 4 \hat{i} + 2 \hat{j}$ and $\vec{B} = 2 \hat{i} + 4 \hat{j}$ .

When you ride a bicycle at constant speed, nearly all the energy you expend goes into the work you do against the drag force of the air. Model a cyclist as having cross-section area $0.45 m^{2}$ and, because the human body is not aerodynamically shaped, a drag coefficient of $0.90$ .

a. What is the cyclist’s power output while riding at a steady $7.3 m / s (16 m p h)$ ?

b. Metabolic power is the rate at which your body “burns” fuel to power your activities. For many activities, your body is roughly $25 %$ efficient at converting the chemical energy of food into mechanical energy. What is the cyclist’s metabolic power while cycling at $7.3 m / s$ ?

c. The food calorie is equivalent to $4190 J .$ How many calories does the cyclist burn if he rides over level ground at $7.3 m / s f o r 1 h r$ ?

A $90 k g$ firefighter needs to climb the stairs of a $20 m$ -tall building while carrying a $40 k g$ backpack filled with gear. How much power does he need to reach the top in $55 s$ ?

A horizontal spring with spring constant $85$ N/m extends outward from a wall just above floor level. A $1.5$ kg box sliding across a frictionless floor hits the end of the spring and compresses it $6.5$ cm before the spring expands and shoots the box back out. How fast was the box going when it hit the spring?

A $70$ kg human sprinter can accelerate from rest to $10$ m/s in $3.0$ s. During the same time interval, a $30$ kg greyhound can go from rest to $20$ m/s. What is the average power output of each? Average power over a time interval $∆ t$ is $\frac{∆ E}{∆ t}$
