Answer:
Impulse = 48 kg m/s
Gain in momentum = 48 kg m/s
Explanation:
Force (F) = 6N
Time (t) = 8
Mass (m) = 3 kg
Final velocity (v) = ?
Initial velocity (u) = 0 m/s
First, find acceleration
F = m * a
a = F / m
a = 6 / 3
a = 2 m/s^2
Now, find final velocity
v = u + a * t
v = 0 + 2 * 8
v = 16 m/s
Now, find impulse
Impulse = change in momentum
Impulse = final momentum - initial momentum
Impulse = m * v - m * u
Impulse = m ( v - u )
Impulse = 3 ( 16 - 0 )
Impulse = 48 kg m/s
Here, gain in momentum is same as impulse.
Answer with Explanation:
We are given that
a.x=-0.2 m
Where 
Net electric field=E+E'=4500+1237.5=5737.5 N/C
b.x=0.20 m
Net electric field=E-E'=4500-1237.5=3262.5 N/C
c.y=0.20 m
E=1237.5 N/C
Net electric field=
To find the acceleration, we will use the formula
F=ma
Here the net force will be 40N (50 - 10)
F = ma
40 = 4a
40/4 = a
10 m/s^2 = a
Hope you understood !
The answer is 3.
When a ball is thrown into the air, there is no friction (there's nothing rubbing against it), so the only force acting on the ball is gravity, which aims to pull the ball back down. Since this is the only force, the answer will equal the gravity acting on the ball. Since "weight" is defined as just that (the gravity acting on something), the answer is 3, the magnitude of the rock's weight (or the force of gravity).
