1. Suppose a Jogger has to exert a force of 29N against air resistance to maintain a velocity of +4.0m/s. At what rate is the jogger expending energy?2. P= F*(tf-ti)3. Attempt solution was
P= 116kgm/s
P= 116kgm/s
The units are wrong for power. What do you get if you multiply Newtons by m/s?Nick1234284 said:1. Suppose a Jogger has to exert a force of 29N against air resistance to maintain a velocity of +4.0m/s. At what rate is the jogger expending energy?2. P= F*(tf-ti)3. Attempt solution was

The purpose of practicing physics is to understand the fundamental laws and principles that govern the behavior of matter and energy in the universe. By applying these laws, we can predict and explain the behavior of various physical phenomena, from the motion of objects to the structure of atoms.
The first step in solving a physics problem is to carefully read and understand the problem, identifying the given information and what needs to be solved for. Then, you can use mathematical equations and principles to analyze the problem and come up with a solution. It is important to check your answer and make sure it is reasonable and follows the laws of physics.
Experimentation is a crucial aspect of practicing physics. It allows scientists to test and validate theories and hypotheses, and to gather data that can be used to make predictions and further understand the physical world. Without experimentation, physics would be limited to theories and equations without any real-world application.
The practice of physics has a wide range of applications in other fields of study, such as engineering, astronomy, and medicine. By understanding the principles of physics, we can design and build new technologies, explore the universe, and improve medical treatments and technologies.
To improve your understanding and skills in practicing physics, it is important to actively engage in problem solving and experimentation. Practice regularly and seek out challenging problems to work on. You can also seek help from teachers, professors, or online resources when needed. It is also beneficial to read and stay updated on new developments and discoveries in the field of physics.
