Answer 1

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

Answer 2

Answer:

0.8Ns

Step-by-step explanation:

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

Initial velocity =
