An object starts from position X = 0 and moves along a straight line with its position given by; X = 20t - 5t^3 where t is the time taken to reach position X.
Find;
i) The time at which the velocity is zero
ii) The time at which the acceleration is zero
iii) The average velocity over the first three seconds of motion
No answers were given with the questions, so would appreciate some answers to check against mine. I have 1.15s, 0s and -50m/s
