An 80.0 N force accelerates a 6.0 kg object from 4.0 m/s to 8.0 m/s. What is the impulse?
0 24 N"s
0 3.33 Nºs
30 N's
0 -30 N's
0-24 N's

24kgm/s

Explanation:

Given parameters:

Force  = 80N

Mass of object  = 6kg

Initial velocity  = 4m/s

Final velocity = 8m/s

Solution:

Impulse  = ?

Solution:

The impulse on a body is its change in momentum.

    Impulse  = m (v  - u )

m is the mass

v is the final velocity

u is the initial velocity

  Now insert the parameters and solve;

          Impulse  = 6 (8 - 4) = 24kgm/s

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
