Answer:
Vi = 4.38 m/s
Explanation:
Given
m = 1000 kg ;
y = 8m ;
T = 11000 N;
∑Fy = m*a
W - T = m * a
(1000kg * 9.8 m/s² ) - 11000N = 1000 kg * a
a = - 1.2 m/s²
Using the equation from parabolic motion
Vf ² = Vi² + 2*a*y
Solve to Vi
Vi = √ 2* 1.2m/s² * 8 m
Vi = √19.2 m²/s²
Vi = 4.38 m/s
I am not sure what you are asking but..: A series circuit is a circuit with 2 or more bulbs or lights to light. In a series circuit when you take out one bulb (or one goes out) the rest go out as well. A parallel circuit is still multiple lights, but because of the way it is set up makes it so when you take out one bulb (or one goes out) all of the rest stay lit.
Should be -9.8m/s^2!!! The force of gravity is the only thing pushing it down!!
Hope I helped you out!!
Answer:
<em>J=600 kg m/s
</em>
Explanation:
<u>Impulse And Momentum
</u>
Suppose a particle is moving at a certain speed and changes it to . The impulse J is equivalent to the change of linear momentum. The momentum can be computed by
The initial and final momentums are given, respectively, by:
Thus, the change of momentum is
It's equal to the Impulse J
Our data is
