Use separation of variables to nd the solution to the differential equation subject to the initial oonclition u(0) = 1. Mt) = ' The acceleration of an object moving along a coordinate line is given by a(t) = (4t + 3) in meters per second per second. If the velocity at t = 0 is 4 meters per second, find the velocity 2 seconds later. U = meters per second See Example 4 page 207 for a similar example.An object at the origin at time t = 0 has velocity, measured in meters per second, if 0
