Question

The position of a particle which moves along a straight line is given ;
X = t³-6t²-15t+60

Determine;
1) the time at which the velocity will be zero
2) the position and distance traveled by the particle at that time
3) the acceleration if the particle at that time

Answer 1

answers 1)at 5seconds

2)position x=-40m ,distance covered =100m

3)acceleration =18m/sec^2
