The figure gives the acceleration a versus time t for a particle moving along an x-axis. The a-axis scale is set by as = 15.0 m/s2. At t = -2.0 s, the particle's velocity is 11.0 m/s. What is its velocity at t = 6.0 s?

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
