2. 2. The position y of a particle moving along the y axis depends on the time t according to the equation The dimensions of the quantities A and B are respectively

3. 3. An aluminum cylinder of density 2.70 g/cm**3, a radius of 2.30 cm, and a height of 1.40 m has the mass (kg) of ?

4. Ch2 1. Fig 1 shows the position-time graph of an object. What is the average velocity of the object between t=0.0 s and t= 5.0 s?

5. 2. A particle starts from the origin at t = 0 and moves along the positive x-axis. A graph of the velocity of the particle as a function of time is show in Fig 1. The average velocity of the particle between t = 0.0 s and 5.0 s is

6. 3. The position of a particle moving along the x axis is described by the equation x(t) = 5.0 + 2.0t + t**3. Find its average acceleration for the time interval t = 1.0 s to t = 2.0 s.

7. 4. A particle moving along the x axis has a position given by x =(24 t - 2 t**3) meters, where t is measured in seconds. How far is the particle from the origin (x=0) when the particle stops momentarily?

8. 5. A stone is thrown downward from height (h) above the ground with an initial speed of 10 m/s. It strikes the ground 3.0 seconds later. Determine h
