A force of 20 N acts upon a block moving at 4 m/s. calculate the mass of the object

The area of a rectangular loop of wire is 3.6 * 10-3 m2. The loop is placed in a magnetic field that changes from 0.20 T to 1.4 T in 1.6 s. The plane of the loop is perpendicular to the direction of the magnetic field.
