The speed of a nerve impulse in the human body is about 100 m/s. If you accidentally stub you toe in the dark, estimate the time it takes the nerve impulse to travel to your brain. (Assume that you are approximately 2.00 m tall and that the nerve impulse travels at uniform speed.)

My mutt dog who seems to be a mix of pug, schnauzer, and dachshund, Boomer, likes to eat worms. He spots a juicy one in the grass and takes off from our porch at 5.22 m/s. When he reaches the worm, 8.16 m from our porch, he determines it's not up to his dog standards and decides to let it live another day. How long did it take Boomer to reach the worm, to two decimal places?

An object's position in the as a function of time obeys the equation; x (t) = 3t – 2t³ + 1.5t where all constants have proper SI Units. What is the speed of the object in the x direction at t = 1.75 seconds?

A ball is thrown straight down at 1.29 m/s and hits the ground 1.07 seconds later. How many meters did the ball travel before hitting the ground? Type your answer.

A Boeing 747 "Jumbo Jet" has a length of 64.5 m. The runway on which the plane lands intersects another runway. The width of the intersection is 24.8 m. The plane decelerates through the intersection at a rate of 5.56 m/s2 and clears it with a final speed of 43.1 m/s. How much time is needed for the plane to clear the intersection?

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a person accidentally steps barefoot on a pebble. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the person is 1.60 m tall and the nerve impulse travels at uniform speed.

When they are apart by 425m, the famous twins Isaac and Albert Neuman begin approaching each other. Isaac is riding a bicycle at a speed of 12.7 m/s and Albert is running at a speed of 3.8 m/s. How long does it take for them to meet, and how far will each have traveled?

An object has an initial velocity of 15 m/s. How long must it accelerate at a constant rate of 3 m/s square before it's final velocity is equal to twice it's initial velocity?

A rocket is shot straight up in the air from the ground at a rate of 46 feet per second. The rocket is tracked by a rangefinder that is 427 feet from the launch pad. Let d represent the distance from the rocket to the rangefinder and t represent the time, in seconds, since "blastoff". Express d as a function of t.

A muon (an elementary particle) enters a region with a speed of 5.45 x 106 m/s and then is slowed at the rate of 1.30 x 1014 m/s².
