Solution of a) |
|
|
|
Take the time derivative of the position to get an equation for the velocity as a function of time: v(t) = dx(t)/dt = d(0.3 t2 - 0.2 t3)/dt v(t) = 0.6 t - 0.6 t2 m/s

 Arm motion from 1≤ t ≤ 1.5 seconds |
Solution of b) |
|
|
Take the time derivative of the velocity to get an equation for the acceleration as a function of time: a(t) = dv(t)/dt = d(0.6 t - 0.6 t2 )/dt a(t) = 0.6 - 1.2 t m/s2 |
