Chapter 3, Problem 1TE

What is the net force on a bright red Mercedes convertible traveling along a straight road at a steady speed of $100\text{km}/\text{h}$ ?

To determine

The net force on a bright red Mercedes.

Answer to Problem 1TE

The net force on a bright red Mercedes is $0\text{N}$

Explanation of Solution

When an object moves with a constant speed it means that there is no variation of speed; thus, the acceleration is equal to zero. As acceleration and force are directly proportional so the net force acting over the object will be zero.

Here, a bright red Mercedes convertible is travelling with a steady speed of $100\text{km}/\text{h}$ , which means that the acceleration of the car will be zero. As the acceleration on the car is zero, the net force acting on the Mercedes is also zero.

Conclusion:

Therefore, the net force on a bright red Mercedes is $0\text{N}$ .
