2: If I walk 15 meters East and then 15 meters North and my total trip takes 10 seconds, what is my average velocity? A) 0 m/s B) 2.12 m/s NE C) 3.00 m/s NE D) 21 2 m/s NE

10) An advertisement for the newest model of a Mercedes sports claims the car can go from 0 to 60 miles per hour (mph) in just 3.3 seconds! a) How many meters per second (m/s) is 60 mph? b) In m/s² (sometimes written as m/s/s also, just so you know), what is the supposed acceleration of the sports car?

9. A particle currently has positive displacement and negative velocity and always has constant positive acceleration. Which one of the following statements must be true about the particle? A. Its speed is currently increasing. B. Its speed is currently decreasing. C. Its velocity will always be negative. D. Its displacement will eventually become negative.

3.) graph is given. The following position -vs- time +40 +30 Position +20 x (m) +10 0 5 10 15 20 25 30 Time t(s) A.) Determine the instantaneous velocity at t = 2 s. B.) velocity at t = 16 s. C.) Determine the instantaneous Draw a velocity -vs-time graph.

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

6) A car travels 120 Km at 80 Km/h and 70 Km at 100 Km/h. What is the average speed of the car? A) 91.1Km/h B) 89.6Km/h C) 96.4Km/h D) 84.6Km/h

2.) A buggy car starts at 10 m and travels in the +x direction with a constant velocity of 1.5 m/s for 4 s. The car immediately stops for 3 s and turns around and travels in the opposite direction with a constant velocity of 2 m/s for 10 s. a. Draw a position -vs- time graph and velocity -vs- time graph.

Number 84 how do you find the average velocity ? Is this reasonable time ? Explain

Young Hector launches a 200 gram block uphill on a frictionless ramp which is tilted at 30 degrees with the horizontal, as shown in the Figure. At the instant of its launch, the block is moving uphill at 4.00 m/s. Hector observes as the block travels a distance of 50.0 cm uphill on the ramp. In the following, consider the period of time during which the block moves uphill through the 50.0 cm distance shown in the Figure. For simplicity, assume that g = 9.80 m/2. d (50.0 cm) 4.00 m/s h 30°

A car goes at 60 mph for 2 hours from point O and then it takes 3 hours to get back to point O. a) Find the average velocity for the entire trip. b) Find the average velocity for the first 3 hours. c) Find the average speed for the whole trip.
