the speed of a nerve impulse in the human body is baout 100m/s. if you accidentally stub your toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. Please put full solution
12. Car B is traveling a distance d ahead of car A. Both cars are traveling at 60 t%s when the driver of B suddenly applies the brakes, causing his car to decelerate at 12 /32. It takes the driver of car A 0.75 s to react (this is the normal reaction time for drivers). When he applies his brakes, he decelerates at 151/,2. Determine the minimum distance d be tween the cars so as to avoid a collision. (Practice at Home) A B

One of my questions got solved and helped me so much thank you! Here’s another one please. Two trains are 9.82km apart. They travel in opposite directions, to each other. Train A has a speed of 5.87 km/h at departure and an acceleration of 0.29m/s squared. Train B has a speed of 20.3m/s at the start and an acceleration of 0.69m/s squared. B. Determine when the trains meet.
My pug/bulldog mix, Georgia, who is blind and deaf, gets a whiff of her dinner. As soon as it registers to her that it's dinnertime, she runs 4.12 meters from the middle of our living room to our kitchen, where she is satiated with her grub. If it takes her 4.45 s to get to the kitchen, what was her speed in m/s to the nearest hundredth?
