Given a particle that follows the acceleration a(t) 10 (-t + 2 ) (t-5)+ 100 m/s2, find: a. find the displacement at 2 seconds. assume from rest and a starting point of 3m. b. find the velocity at 4 seconds. assume an initially at rest. c. find the time at which maximum displacement occurs (use calculus because it is way easier, not kinematics). d. find the value of maximum velocity over the interval 0
