Bb8 is an intergalactic robot (essentially a soccer ball with a half meter radius that can control how fast it rolls around) that is trying out for a new role in the rebellion. one of the tests is how fast they can travel 100 m. they must start from rest and end at rest. bb8 has a maximum angular acceleration rate of 2 rad/s2, both when speeding up and slowing down. what is the minimum time bb8 can run the trial?

20 seconds

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

r = Radius of robot = 0.5 m

= Angular acceleration = 2 rad/s²

Linear acceleration is given by

While speeding up time taken is 10 seconds

The time taken to slow down is 10 seconds

Total time the trial is rum is 10+10 = 20 seconds
