5. A helicopter pilot at an airport is told to fly a distance, d at a speed v directly east to pick up a stranded hiker. However, he sees no hiker when he arrives. Radioing the control tower, he learns that the hiker is actually a distance, d west of the airport. The pilot turns around and heads straight for the hiker at a speed that is 50% faster than his speed during the initial segment of...

A. Dr. Kit (Honors) is lost and drives his Honda Accord at 22 mph for 80 minutes and then at 43 mph for 27 minutes. How far did he travel? (include units with answer) HINT: Use the Definition of Speed------- Speed = Distance/Time B. Dr. Pionke (Honors Emeritus) has some errands to run so he drives his bimmer at 22 mph for 109 miles and at 43 mph for 186 miles. How long did his trip last? (include units with...

A young boy called Nick is stranded at the airport with his father, Tom, because of bad weather. To pass the time, they decide to have a race. The race is an out-and-back race, starting and ending at the same place. Tom runs at constant speed a distance L, and then turns around and comes back. Nick, because he is so young, gets an advantage: while running away from the start line, he...

1. A train at a constant 62.0 km/h moves east for 32.0 min, then in a direction 46.0° east of due north for 29.0 min, and then west for 42.0 min. What are the (a) magnitude and (b) angle (relative to east) of its average velocity during this trip? 2. A cart is propelled over an XX plane with acceleration components ax 5.5 m/s2 and ay = -2.3 m/s. Its initial velocity has components vox = 9.3 m/s and voy...

Background: Jerome and Paul are competitive brothers. They live on a small farm on the northern bank of a river that runs purely east and west and that flows to the east at a rate of 1.400 m/s . The brothers have run some time trials on the farm pond, and they know that, in still water, Jerome can paddle the family canoe at a steady rate of 2.950 m/s for a considerable length of time. When younger brother Paul runs a...
