An object is moving along the x-axis. at t = 0 it has velocity v0x = 20.0 m/s. starting at time t = 0 it has acceleration ax = - ct, where c has units of m/s3. (a) what is the value of c if the object stops in 8.00 s after t = 0? (b) for the value of c calculated in part (a), how far does the object travel during the 8.00 s?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
