The position coordinate of a particle which is confirmed to move along a straight

line is given by: = 23 − 8 + 6

Where x is measured in metres, and t is in seconds.

Evaluate

• The total distance travelled by the particle at t = 5 s.

[4 marks]

• The velocity of the particle at t = 10 s.

[4 marks]

• The acceleration of the particle at t = 7 s
