Suppose it takes you 2 minutes and 13 seconds to swim 8 lengths of a 25.0 meter swimming pool (out and back 4 times, ending up where you started). What is your average velocity during this time interval? What is your average speed during this time interval? options: 0 m/s 3.0 m/s 1.5 m/s

A breaststroke competition consists of swimming back to the opposite end and back to where you started. Suppose a swimmer completes the first 50 m of the 100 m breaststroke in 39.1 seconds. When he reaches the opposite end of the 50 m long pool, he turns back and swims to the starting point in 42.5 seconds. What is the swimmer's average speed for the return leg only?a) 1.18 m / sb) 1.23 m / sc) 0.12 m / sd) 0 m / s

You are driving through town at 10.0 m/sm/s when suddenly a ball rolls out in front of you. You apply the brakes and begin decelerating at 3.2 m/s2m/s2.A) How far do you travel before stopping? (Already Answered it's 16m)B)

A whale swims due east for a distance of 8.0 km in a time of 2.50 h. It then turns around and moves west for 2.0 km in a time of 0.50 h. It turns around again and heads 4.0 km due east in a time of 1.00 h. What is the total distance travelled by the whale. What is the total displacement? What is the average speed for the entire trip? What is the average velocity for the entire trip? There are five quantities discussed in this question: distance, displacement, time, speed, and velocity. Which of these are scalars and which are vectors?

You have already traveled 30 miles east and then 30 miles north. To get back to the start, you travel 30 miles west in 1 hour and then 30 miles south in a half hour. What are your average speed and average velocity for the whole rally? Explain your answer.

A woman backs her van out of her parking space with a constant acceleration of 1.8 m/s2. Assume that her initial motion is in the positive direction. Part A: How long does it take her to reach a speed of 2.1 m/s in seconds?  Part B: If she then brakes to a stop in 0.65 s, what is her acceleration in meters per square second?

You are driving home from school steadily at 99 km/h for 190 km . It then begins to rain and you slow to 63 km/h instantly. You arrive home after driving 5.0 hours. How far is your hometown from school?Express your answer using two significant figures. What was your average speed?Express your answer using two significant figures.

We are standing on the top of a 1040 feet tall building and launch a small object upward. The object's height, measured in feet, after t seconds is h(t) = 16t? + 128t + 1040. A) What is the object initial velocity? ft/second B) What is the highest point that the object reaches? feet

Bartholomew jogs from home at 3.50 m/s north for 1380 seconds. Then, he turns around and jogs 2.40 m/s east for 875 seconds.  A) Assuming an original position of zero, where is Bartholomew now? B) What is his average velocity? C) If a third part of his jog returns him home in 985 seconds, what should his velocity be on this part?

Ilya and Anya each can run at a speed of 8.00 mphmph and walk at a speed of 3.10 mphmph . They set off together on a route of length 5.00 milesmiles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half.   A.) How long does it take Anya to cover the distance of 5.00 milesmiles ? Express your answer numerically, in minutes.   B.) Find Anya's average speed. Express Anya's average speed save,Anyasave,Anya numerically, in miles per hour.   C.) How long does it take Ilya to cover the distance? Express the time tIlyatIlya taken by Ilya numerically, in minutes.   D.) Now find Ilya's average speed. Express Ilya's average speed save,Ilyasave,Ilya numerically, in miles per hour.
