Now let’s apply our definition of average velocity to a swimming competition. During one heat of a swim meet, a swimmer performs the crawl stroke in a pool 50.0 mm long, as shown in (Figure 1). She swims a length at racing speed, taking 24.0 ss to cover the length of the pool. She then takes twice that time to swim casually back to her starting point. Find (a) her average velocity for each length and (b) her average velocity for the entire swim. c) If the swimmer could cross a 15 kmkm channel maintaining the same average velocity as for the first 50 mm in the pool, how long would it take?
You drive a beat-up pickup truck down a straight road for 5.2 mi at 43 mi/h, at which point yourun out of fuel. You walk 1.2 mi farther, to the nearest gas station, in 27 min (= 0.450 h). What isyour average velocity from the time you started your truck to the time that you arrived at thestation?
A car travels along a straight line at a constant spped of 60 mi/h for a distance d and then another distance d in the same direction at another constant speed. the average velocity for the entire trip os 30mi/h.what is the constant speed with which the car moved during the second distance d?
An object is moving in the positive direction along thex - axis. Sketch plots of the object’s position vs. time and velocityvs. time if (a) its speed is constant, (b) it’s speeding up ata constant rate, and (c) it’s slowing down at a constant rate.
I am having trouble with an average speed problem. The problem states that a person walks at 4.5 meters per second from point a to b. Then walks back from point b to a at a speed of 3.2 m/s. I know that average speed is displacement/time. However I am not sure how to calculate time or displacement from the two givens. The problem also gives that the average velocity is 0.
A football quarterback runs 13.7 m straight down the playing field in 2.50 s. He is then hit and pushed 3.00 m straight backward in 2.10 s. He breaks the tackle and runs straight forward another 18.3 m in 5.20 s. Calculate his average velocity for each of the three intervals and for the entire motion. (Define the positive direction to be the direction of initial motion.) What is his average velocity over the entire motion? AFCpERr I
The acceleration of a particle is given by a - 2t - 17, where a is in meters per second squared and tis in seconds. Determine the velocity and displacement as functions of time. The initial displacement at t= 0 is so = -2 m, and the initial velocity is vo = 4 m/s. Once you have determined the functions of time, answer the questions. Questions: When t = 5.9 s, m i m/s m/s?
A student begins at rest and then walks north at a speed of v1=0.65m/s. The student then turns south and walks at a speed of v2=0.28m/s. Take north to be the positive direction. a)What is the student's overall average velocity vavg, in meters per second, for the full trip assuming the student spent equal times at speeds v1 and v2? b) If the student travels in the stated directions for 30.0s30.0s at speed v1 and 20.0s at speed v2, what is the net displacement, in meters, during the trip? c) If it takes the student 1.2s to reach the speed v1, from rest, what is the magnitude, in meters per squared second, of the student’s average acceleration during that time?
