*11. ssm A bicyclist makes a trip that consists of three parts, each in the same direction (due north) along a straight road. During the first part, she rides for 22 minutes at an average speed of 7.2 m/s. During the second part, she rides for 36 minutes at an average speed of 5.1 m/s. Finally, dur- ing the third part, she rides for 8.0 minutes at an average speed of 13 m/s. (a) How far has the bicyclist traveled during the entire trip? (b) What is her average velocity for the trip?
• Baguio City is approximately 240 km from Manila. A bus leaves the station in Manila. Because of heavy traffic, its speed is only 30.0 km/h for the first 2.0 h. After that, it travels at 50 km/h until it reaches Baguio City. It travels at night on its return trip, covering the distance in only 4.0 h. (a) What is its average speed for the round trip? (b) What is its average velocity for the round trip? Express your answers in m/s.
On a 200 km bike cycle ride, you ride the first 90 km at an average speed of 20 m/s. What mustyour average speed over the next 40 km be to have your average speed for the total 200 km be?(b) Given this average speed for the first 90 km, can you possibly attain an average speed of80 m/s for the total 200 km ride? Explain.

• In heavy rush-hour traffic you drive in a straight line at 12 m>sfor 1.5 minutes, then you have to stop for 3.5 minutes, and finallyyou drive at 15 m>s for another 2.5 minutes. (a) Plot a positionversus-time graph for this motion. Your plot should extend from t = 0 to t = 7.5 minutes. (b) Use your plot from part (a) to calculate the average velocity between t = 0 and t = 7.5 minutes.
3. A jogger runs along a straight and level road for a distance of 8.0 km andthen runs back to her starting point. The time for this round-trip is 2.0 h.Which one of the following statements is true? (a) Her average speed is8.0 km/h, but there is not enough information to determine her average velocity. (b) Her average speed is 8.0 km/h, and her average velocity is8.0 km/h. (c) Her average speed is 8.0 km/h, and her average velocity is0 km/h.
At time t=0.0s a particle is located at x = 4.0 m and y = 1.0 m. The particle has an initial velocity at t=0.0 s given by: v=6.0m/si-2.0m/sj The particle experiences a constant acceleration beginning at t=0.0s that can be described by a = -2.0m/s² i +5.0m/s23 +3.0m/s² k (A) On coordinate axes (x and y) show the particle initial position and draw a vector which indicates the initial velocity of the particle. (B) If we want to determine the position of the particle at a later time t, which physics approach or equation(s) might we use to do so? (C) Find the position of the particle at t=4.0 s. Express your result in terms of the position vector in and j and k notation.
You travel from point A to point B in a car moving at a constant speed of 70km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90km/h. Is your average speed for theentire trip from A to C equal to 80km/h. Explain why or why not.
Could I have help with this average speed and velocity problem. I already know the answers"average velocity = 2.7 m/s due east, average speed = 8.0 m/s" but I need a detailed explanantion on how and why because I am not understanding and getting the same answers
A circular track has a radius of 120 m. An athlete runs half-way round the track and stops. (i) How much distance has she covered? (ii) Calculate her displacement. She takes 54 s to cover the distance. (iii) Calculate her average speed, using the formula average speed = distance covered time taken (iv) Calculate her average velocity using the formula average velocity = displacement time taken
