Introductory Skills Question 1 (1 point) A spherical solid ball with uniform mass density has a radius of 2 meters and a total mass of 8 kilograms. How much mass would another ball made of the same material have if its radius were 1 meter(s)? The volume of a sphere is (4/3) Enter your answer in units of kg rounding to two decimal places.

The y axis scale is set by a=+60 meters and the x axis scale is set by b =+8 seconds. The plot starts at the origin (time=0, position=0). Calculate the slope at t = 7 seconds. Enter your answer in units of m/s rounding to two decimal places. If the slope is negative at t = 7 seconds then you must enter a negative value. Your Answer: AnswerQuestion 4 (1 point) + a b Velocity (m/s) time (s) Shown in the graph is a velocity vs. time graph. The y axis scale is set by a=+120 meters per second and the x axis scale is set by b =+8 seconds. The plot starts at the origin (time=0, velocity=0). Calculate the area underneath the curve for the time period shown. Areas with a positive position must be treated as positive areas, areas with a negative position must be treated as negative areas (as shown in the figure). Enter your answer in units of meters (these are the units of this area) rounding to two decimal places. If the area is negative then you must enter a negative value.
