1.Determine the time required for a car to travel 1 km along a road if the car starts from rest, reaches a max speed at some intermediate point, and then stops at the end of the road. the car can accelerate at 1.5 m/s^2 and decelerates at 2 m/s^2
2.The acceleration of a particle traveling along a straight line is a=(1/5)s^(1/2), s in m, if v=0, s=0 when t=0, determine the particle's velocity at s=6
3.A Particle is traveling on a straight line with velocity v=(3t^2-6t) where t is in sec. if s=4 ft when t=0, determine the position of the particle when t=4s. what is the total distance traveled during time interval t=0 to t=4s?
