Question

if a particle moves in a straight line by the top is equal to 2 x cube + 9 X square + 12 x + 6 velocity of the particle is

Answer 1

Explanation:

2x^3+9x^2+12x+6

Can be differentiated in 6x^2+18x+0+0=0

6x^2=-18x

x=3

Thus velocity is -3m/s (-)sign Indicates that it's in opposite direction
