You may find the following data useful: Acceleration due to gravity: g = 9.80m/s 2 Volume of a cylinder: V = “ r 2 h 1. A steel cylinder is 39 mm in height and 39 mm in diameter. (a) 3 ) 2. An automobile moving along a straight track changes its velocity from 40 m/ s to 80 m/s in a distance of 200 m. What is the (constant) acceleration of the vehicle during this time? a. 8.0 m/s b. 9.6 m/s c. 12 m/s d. 6.9 m/s e. 0.20 m/s 3. An automobile traveling along a straight road increases its speed from 30.0 m/s to 50.0 m/s in a distance of 180 m. If the acceleration is constant, how much time elapses while the auto moves this distance? a. 6.00 s b. 4.50 s c. 3.60 s d. 4.00 s e. 9.00 s 4. A particle starts from rest at x = 0 m and v = 0 m/s and moves for 10 s with an acceleration of +2.0 cm/s2. For the next 20 s, the acceleration of the particle is –1.0 cm/s2. Draw a graph of acceleration vs. time Draw a graph of velocity vs. time Draw a graph of position vs. time What is the position of the particle at the end of this motion? a. zero
