Answer:
Explanation:
We need to use the momentum and energy conservation.
Where:
- m is the mass of bullet (m=0.01 kg)
- M is the mass of the wooden (M=0.75 kg)
- v(0) initial velocity of bullet
- V(1) is the velocity of the combined object in the moment the bullet hist the block
Conservation of energy.
We have kinetic energy at first and kinetic and potential energy at the end.
Here:
- V(1) is the velocity of the combined at the initial position
- h is the vertical height ( h = 0.800 m)
We can find V(2) using the definition of force at this point:
Now, we can solve the equation to find V(2)
Now we can find V(1) using the conservation of energy equation
Finally, using the momentum equation we find v(0)
I hope it helps you!
Answer:
3.004A
Explanation:
The voltage across an inductor is expressed as:
Given
f = 270Hz
V = 48V
L =0.053 H
Get the current
270 = I (2*3.14*270*0.053)
270 = 89.8668I
I = 270/89.8668
I = 3.004A
Hence the current in the inductor is 3.004A
