During which time interval(s) is the object moving with a positive velocity? F A E time В C velocity O O O 0 ONow 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 attached). 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. If the swimmer could cross a 13 kmkm channel maintaining the same average velocity as for the first 50 mm in the pool, how long would it take? Express your answer in hours.

For the speed vs base graph, we will plot the average velocity for each of the ramp angles (20°, 30°, 45°, 60°, and 70°) on the y-axis, and the distance travelled (base) on the x-axis. For the speed vs height graph, we will plot the average velocity for each of the ramp angles on the y-axis, and the height of the ramp on the x-axis. For the speed vs slope graph, we will plot the average velocity for each of the ramp angles on the y-axis, and the slope of the ramp (rise over run) on the x-axis. now using this information creat these 3 graphs for the table down below, Ramp angle in degrees Distance (in m) time 1 (s) time 2 (s) time 3 (s) T-avg Velocity(m/s) 20 1.7 0.8 0.7 0.9 0.8 2.125 m/s 30 1.5 0.9 1.1 1.0 1.0 1.5 m/s 45 2 1.2 1.3 1.4 1.4 1.54 m/s 60 1.8 1.5 1.6 1.7 1.7 1.125 m/s 70 1.9 1.6 1.8 2.0 2.0 1.06 m/sAt t = 0, a truck is traveling east at a constant speed of s = 85.9 km/h.
