Displacement, Velocity, and celeration Answer the following question with solution The speed of a nerve impulse in the human body is about________m/s. If you accidentally stub your toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. A motorist drives north for______minutes at_______minutes. He then continues north, traveling____ km ______h What is his total displacement? What is his average velocity Super Ball traveling at_____ m/s bounces off a brick wall and rebounds at____ m/s. A high-speed camera records this event. If the ball is in contact with the wall for____ ms, what is the magnitude of the average acceleration of the ball during this time interval? The average person passes out at an acceleration of____ g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time would be required for the car to accelerate from rest to_____miles per hour? (The car would need rocket boosters!)
