Question

The figure shows the position-time (x-t) graph of one-dimensional motion of a body of mass 0.4 kg. The magnitude of each impulse is

(a) 0.4 N- s

(b) 0.8 N-s

(c) 1.6 N-s

(d) 0.2 N-s

Answer 1

 Correct option (b) 0.8 N-s
  Explanation:

From the graph, it s a straight line, so uniform motion Because of Impulse direction of velocity changes as can be seen from the slope of the graph.
