A polar bear starts at the North Pole. It travels 1.0 km south, then 1.0 km east, and then 1.0 km north to return to its starting point. This trip takes 45 min. What was the bear's average speed and velocity?

Julie drives 91 mi to Grandmother's house. On the way to Grandmother's house, Julie drives half the distance at 36 mph and half the distance at 56 mph. On her return trip, she drives half the time at 36 mph and half the time at 56 mph. What is Julie's average speed on the way to Grandmother's house?

A racing car reaches a velocity of 52 m/s north. It then uses its parachute and braking system to uniformly slow down and come to rest 5.5 seconds later. What was the displacement, in meters, of the racing car during those 5.5 seconds?

Jason and Eddie are traveling from Atlanta to Miami which is a distance of 662 miles. It took them two hours and 45 mins to get to Valdosta Georgia. Then, they made it from Valdosta to Miami in 8 hours and 30 minutes. what would be Jason and Eddie's average speed for this entire trip?

What is the unit for acceleration? A race car accelerates uniformly from 18.5 m/s to 46.1 m/s in 2.47 seconds. Determine the acceleration of the car. A blue beetle starts from rest and in 4.5 seconds is flying 2.2 m/s. What is the acceleration of this insect?

Joe takes his dog to the local dog park every morning, too. He walks with his dog blocks south, 5 blocks west, and 5 blocks north in order to get to the park. What is his total displacement?

A pilot flies in a straight path for 1 h 30 min. She then makes a course correction, heading 10° to the right of her original course, and flies 2 h in the new direction. If she maintains a constant speed of 500 mi/h, how far is she from her starting position? (Round your answer to the nearest mile.)

The acceleration of an object (in m/s) is given by the function a(t) = 7 sin(t). The initial velocity of the object is v(0) 2 m/s. Round your answers to four decimal places. a) Find an equation v(t) for the object velocity. v(t) = b) Find the object's displacement (in meters) from time 0 to time 3. meters c) Find the total distance traveled by the object from time 0 to time 3. meters

The acceleration of an object (in m/s2) is given by the function a(t)=8sin(t)a(t)=8sin(t). The initial velocity of the object is v(0)=−10v(0)=-10 m/s. Round your answers to four decimal places.a) Find an equation v(t) for the object velocity.v(t)v(t) = −8cos(t)−2Correct  b) Find the object's displacement (in meters) from time 0 to time 3.3.4187Incorrect   metersc) Find the total distance traveled by the object from time 0 to time 3.   meters

A car drives from Mechanicsburg, PA to Carlisle, PA which is 17 km away in 17 minutes. Due to traffic, the return trip takes 30 minutes. What is the average speed for the whole trip? Give you answer in units of m/s to 1 decimal place.
