Motor neurons in mammals transmit signals from the brain to skeletal muscles at approximately 25 m/s. Estimate how much time in milliseconds it will take for a signal to get from your brain to your hand.
A bicyclist heads east at 19 k(m)/(h). After she has traveled 20.4
kilometers, another cyclist sets out in the same direction going
30 k(m)/(h). About how long will it take the second cyclist to
catch up to the first cyclist?
A man decided to ride his car at 10 kph for the first 5 seconds. He then accelerates at 1 m/s for the next 5 seconds, 2 m/s for the next 5 seconds, 3 m/s2 for the next 5 seconds, and so on and so forth.
(a) At what time will he reach a velocity of 60 kph?
(b) What is the total distance (m) traveled after he has reached a velocity of 60 kph?

His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69arrow_forward
- As a city planner, you receive complaints from local residents about the safety of nearby roads and streets. One complaint concerns a stop sign at the corner of Pine Street and 1st Street. Residents complain that the speed limit in the area (89 km/h) is too high to allow vehicles to stop in time. Under normal conditions this is not a problem, but when fog rolls in visibility can reduce to only 47 meters. Because fog is a common occurrence in this region, you decide to investigate. The state highway department states that the effective coefficient of friction between a rolling wheel and asphalt ranges between 0.842 and 0.941, whereas the effective coefficient of friction between a skidding (locked) wheel and asphalt ranges between 0.550 and 0.754. Vehicles of all types travel on the road, from small cars with a mass of 531 kg to large trucks with a mass of 3463 kg. Considering that some drivers will brake properly when slowing down and others will skid to stop, calculate the minimum and…arrow_forwardSuppose hemoglobin and DNA are diffusing in water.

Its body shape can be modeled as a 2-μm-long cylinder with a 1 μm diameter, andit has a mass of 1 x 10-12 g. Its chromosome consists of a single double-stranded chain of DNA 700 times longer than its body length. The bacterium moves at a constant speed of 20 μm/s, though not always in thesame direction. Answer the following questions about E. coli using SI base units (unless specifically requested otherwise) and correct significant figures.a. What is its length?b. Diameter?c. Mass?d. What is the length of its DNA, in millimeters?e. If the organism were to move along a straight path, how many meters would it travel in one day?arrow_forward
- Mr. Pascual and Mr. Reyes decide to go to Batangas using a car and a motorcycle, respectively. They agree to meet at UST st so that they will start traveling at the same time. However, at the time of their meet-up, Mr. Reyes is late and he said Mr. Pascual that he will catch up. Mr. Pascual then left UST and start to travel at an average speed of 45.5 kph. After 19 minutes, Mr. Reyes arrived at UST and started to travel to batangas at an average speed of 67.81 kph. What is the total distance traveled in kilometers by Mr. Reyes by the time he catch up with Mr. Pascual?

You have already stopped and measured the distance between adjacent poles as 40.0 m. You are now driving again and have activated your smartphone stopwatch. You start the stopwatch at t 5 0 as you pass pole #1. At pole #2, the stopwatch reads 10.0 s. At pole #3, the stopwatch reads 25.0 s. Your friend tells you that he was pressing the brake and slowing down the car uni- formly during the entire time interval from pole #1 to pole #3. (a) What was the acceleration of the car between poles #1 and #3? (b) What was the velocity of the car at pole #1? (c) If the motion of the car continues as described, what is the number of the last pole passed before the car comes to rest?arrow_forward
