When you left-click and move Sprite3 over the blue box, the object collides with the box for several ticks, so the impulse is applied multiple times - and that makes it fly off so fast you can't see it move.
so, you need to find a way to apply the impulse only once - by moving the object just above the box (so it will fall on it like the way the right-clicked ones do), or use an instance variable that gets set when the impulse is applied that prevents it from happening again.
Also, the angle of impulse you are using (150) is down to the left (180 would be straight to the left). Your picture shows you want an upward impulse, so I was using 255 degrees and an impulse of 4 to get something close to what you are after. I also set the velocity to 0,0 just before applying the impulse and that gave more consistent results.
