A runner is running around rectangular track with length = 50 meters and width = 20 meters. He travels around rectangular track twice, finally running back to starting point. If the total time he takes to run around the track is 100 seconds, determine average speed and average velocity.

A fox is chasing a bunny. The bunny is initially hopping east at 7 m/s when it first sees the fox. Over the next half second the bunny changes its velocity to west at 10 m/s and escapes. What was the bunny's average acceleration (magnitude and direction) during this half-second interval?

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.

Two bikers are cycling from the Greater Toronto Area to Kingston. The first biker, Merckx, started 200 kilometers (KMs) away from Kingston. The second, Froome started 20KM behind Merckx. Both cyclists start out slowly, but Merckx suffers a bike fault delaying them from starting for 11 hours and giving Froome a head start. Assuming the bikers match the below speed representing the maximum speeds of each biker from the time they begin moving, which biker will reach Kingston first and when? Which of the following answer is correct: a) Merckx in 36.2 hours b) Merckx in 31.2 hours  c) Froome in 38.7 hours d) Froome in 35.6 hours

A cart is given an initial velocity of 5 m/s and experiences a constant acceleration of 2.4 m/s?. What is the magnitude of the cart's displacement during the first 11s of its motion?

Nerve impulses in a human body travel at a speed of about 100 m/s. Suppose a woman accidentally steps barefoot on a thumbtack. About how much time does it take the nerve impulse to travel from the foot to the brain (in s)? Assume the woman is 1.80 m tall and the nerve impulse travels at uniform speed.

An Australian magpie (Gymnorhina tibicen) flies 53 m south and then 47 m west, in a total time of 35 minutes. What is its displacement from the starting position? Enter only the numerical part of your answer (in m) to the nearest integer.

A cart is given an initial velocity of 8.3 m/s and experiences a constant acceleration of 3.3 m/s?. What is the magnitude of the cart's displacement during the first 7 s of its motion?

George, the absent-minded professor, drives his car 5.0 miles due east alonga straight road to the grocery store. Upon arriving there 15 minutes (0.25 h) after he left home, he suddenly realizes he forgot his grocery list. He immediately turns around and heads back towards home. After travelling 6.8 miles due west in 12 minutes (0.20 h), the car runs out of gas. What is his average speed during the not-quite-completed trip?

An Australian emu is running due north in a straight line at a speed of 13.0 m/s and slows down to a speed of 9.70 m/s in 2.30 s. (a) What is the magnitude and direction of the bird’s acceleration? (b) Assuming that the acceleration remains the same, what is the bird’s velocity after an additional 1.30 s has elapsed?
