Given:
F = 39 N, the force applied
t = 2 s, the time interval in which the force is applied.
By definition, the impulse is

Answer: 78 N-s
I'm sorry, but this is not a question. What do you need to know?
Answer:
Explanation:
check attached image for figure, there is supposed to be a figure for this question containing a distance(height of collar at position A) but i will assume 0.2m or 200mm
Consider the energy equilibrium of the system

Here, F is the force acting on the collar,
is the height of the collar at position A, m is the mass of the collar C, g is the acceleration due to gravity,
is the velocity of the collar at position B, and
is the velocity of the collar at A
Substitute 14.4N for F, 0.2m for
, 1.5kg for m,
for g and 0 for 

Therefore, the velocity at which the collar strikes the end B is 4.412m/s
An electric force exists between the following:
-Two negative objects
-Two positive objects
-A negative object and a positive object
