**math(mechanics)**

the velocity of a particle traveling in a straight line is given by v=(6t-3t^2)m/s, where t is in seconds, if s=0 when t= 0. determine the particles deceleration and position when t=3s. how far has the particle traveled during the 3s time interval and what is its average speed?

**math(mechanics)**

the acceleration of a particle as it moves along a straight line is given by a=(2t-1)m/s^2, where t is in seconds.if s=1m and v= 2m/s when t=0,determine the particles velocity and position when t=6s. Also, determine the total distance the particle travels during this time period.

**dynamics**

traveling with an initial speed of 70km/h. a car accelerates at 6000km/hr^2 along a straight road. how long will it take to reach a speed of 120km/hr? also, through what distance does the car travel during this time.?
