A karate chop delivers a force of 3000 N to a board that breaks. The force that the board exerts on the hand during this event is:
- Less than 3000 N
- 3000 N
- more than 3000 N
- need more information
Why is the answer b? Why is the board exerting a force back? Since the chop broke the board wouldn't the answer be a?
Homework Answers
correct answer is b,
because karate chop is the case of impulse force which acts very fast.as Newton's third law states every action has equal and opposite reaction.so if karate chop delivers a force of 3000N on the board so it also experiences the same amount of force.

A javelin thrower exerts a horizontal force of 300 N on a 3 kg javelin during the execution of a throw (assume vertical force is equal to 0 N). Over the course of the throw, his hand and the javelin move through a horizontal displacement of 2.0 m. If the javelin’s initial horizontal velocity is equal to 0 m/s, how would the gravitational potential energy change over the course of the throw? a. Gravitational potential energy will increase b. Gravitational...

Materials fracture when the force per unit area, called STRESS, exceeds a critical value. In general, the critical stress depends on the direction as well as the magnitude of the force. For example, bones break differently when subjected to torsional (twisting) stress than when subjected to compressional (or squeezing) stress. Let us consider compressional stress. Wet human bone for 20-39 year olds has an ultimate compressive strength of 1.6x104N/cm2 [8]. Consider a person who falls from a height to the...

Suppose that 905 smokers each
received a nicotine patch, which delivers nicotine to the
bloodstream at a much slower rate than cigarettes do. Dosage was
decreased to 0 over a 12 week period. Of these 905 people, 255 were

part 1 Does a chemical or physical change force the bullet out of a gun? Would the smoke coming out of the end of the gun most likely a homogeneous or heterogeneous mixture? Explain your answers. Part 2 Scientific facts are measurements. They are not changeable, nor are they subject to interpretation. However, with any measurement, in science, there is a certain amount of uncertainty. This uncertainty is made up in two basic ideas: accuracy and precision. In the real...
