5 A particle moves horizontally in a straight line according to the rule
x(t) = t^3 − 5t^2 + 3t − 5, 0 ≤ t ≤ 7
where x metres is its displacement to the right of the origin at time t seconds.
a What is the initial position of the particle?
b After how many seconds does the particle pass through the origin, correct to 2 decimal
places?
i need help on part b. could some one help me please?
thank you
