Question

a body of mass 2 kg moving with velocity for metre per second is acted upon by a force of 6 Newton opposite with motion coefficient of friction between the body and surface is 0.1 kg is equal to 10 metre per second square its displacement after 4 second is a) 2m b) 9m c) 7m d) 11m​

Answer 1

Explanation:

If A= 3 1 −1 2 , I = 1 0 0 1 and O = 0 0 0 0 , show that A( − 5A + 7I = 0. Hence find A
