Question

The displacement-time graph of a uniformly accelerating body of mass 2 kg, initially at rest, The magnitude of force acting on the body is

Answer 1

elocity of mirror = (velocity of object + velocity of image)/2 Or velocity of image = 2vm – vo = 2(2i + 3j + 4k) – (k) = 4i + 6j + 8k – k = 4i + 6j + 7k
