8. a bowling ball rolls 32 meters in 0.8 seconds. find the average speed (n m/s) of the bowling ball in m/s. 9. a car accelerates from 3.5 m/s to 17 m/s in 4.5 seconds. find the acceleration of the car in m/s 10. rank the following from lowest to highest the support force on you standing in an elevator at rest. b. the support force on you standing in an elevator accelerating upward (highest) the support force on you standing in an elevator accelerating downward a. c. 11. describe the speed and acceleration of the ball released from the top of the track shown in the figure below

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
