Textbook Question
Chapter 2, Problem 13P
. At the end of Section 1.4, we mentioned that the maximum acceleration of a fist during a particular karate blow was measured to be about 3,500 m/s2 just before impact with the concrete block. If the mass of the fist was approximately 0.7 kg, what was the maximum force delivered to the concrete block?

A rope weighs 600 grams per meter of length. What is the weight in kilograms of 12.2 meters of this rope? (1 kilograms = 1000 grams)
In Section 1.4, we considered the collision of a karate expert’s hand with a concrete block. Based on the graphs in Figure 1.31, the initial downward speed of the fist with mass 0.75 kg is about −13 m/s and the collision time is approximately 25 ms. Find the impulse and the average force exerted on the block by the fist during the collision.

- The U.S. quarter has a mass of 5.67 g and a thickness of 1.50 mm. How may pounds would a stack of quarters weigh if you stacked them as high as the Eiffel Tower?

The truck and the car move forward together with a maximum forward force of 18,470 N. Assuming friction is zero, what is the magnitude of the force (in N) of the car's bumper on the truck's bumper? Hullo, everyone! I actually know the answer to this question, because I keep getting it marked as wrong - the answer is supposed to be 4178, but for the life of me, I can't figure out how. I thought it would be as simple as finding the acceleration, then multiplying by mass, but I've tried converting kg to g, tried the law of equal and oppositie reaction, tried the car's mass, tried the truck's mass, but I never even get close to the answer I've been given. The AI function on Bartleby, which I have often found quite useful, also can't get 4178. If anyone could send me the specific steps involved in getting this answer, I would be so grateful - thank you so much!
