The kinetic energy decreases
Hello :))
Mass is dependent on the inertia of an object:))
Hope this helps
Answer:
The object is moving away from the origin
The object started at 2 meters
The object is traveling at a constant velocity
Explanation:
Explanation:
Given that,
Mass of a ball, m = 250 g = 0.25 kg
Initial velocity of the ball, u = 6 m/s
Final velocity of the ball, v = -9 m/s
(a) Impulse of the system is given by :
Impulse = change in momentum
J = m(v-u)
J = 0.25(-9-6)
= -3.75 kg-m/s
(b) Impulse = Ft
If t = 0.5 min = 30 s
So,

So, impulse of the system is -3.75 kg-m/s and the force is -0.125 N.
