Please help me solve

The acceleration of an object (in m/s2) is given by the function a(t) = 9 sin(t). The initial velocity of the object is v(0) = -4 m/s. Round your answers to four decimal places. a) Find an equation v(t) for the object velocity. v(t ) b) Find the object's displacement (in meters) from time 0 to time 3. meters c) Find the total distance traveled by the object from time 0 to time 3. meters
