engineering mechanics kinematics of a particle
1. The v-s graph for a rocket sled is shown. Determine the acceleration of the sled when s = 100 m and s = 175 m.
(A): a100 = 0.333 m/s2, a175 = -1.000 m/s2
(B): a100 = 11.11 m/s2, a175 = -25.0 m/s2
(C): a100 = 3.75 m/s2, a175 = -1.250 m/s2
(D): a100 = 33.3 m/s2, a175 = -25 m/s2
