A time-dependent force, Fvecbold = (7.50i hat bold ? 4.05tj hat bold), where Fvecbold is in newtons and t is in seconds, is exerted on a 2.00-kg object initially at rest.
(a) At what time will the object be moving with a speed of 15.0 m/s?
(b) How far is the object from its initial position when its speed is 15.0 m/s?
(c) Through what total displacement has the object traveled at this moment?
