The position of a particle is given by the equation
𝑥(𝑡)=2𝑡^3−18𝑡^2+42𝑡
Where t is measured in seconds and x in meters.
Draw a diagram to represent the motion of the particle.
Find the velocity at t = 3 s.
When is the particle at rest?
Find the acceleration at t = 4 s.
When is particle moving forward (that is, in the (+) x-direction)?
When is the particle speeding up? When is it slowing down?
