Answer:
By dropping a pencil from a certain fixed height again and again it will make the target super messay with marks of dot everywhere on the target and some even out side the target.
Explanation:
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:
Nothing
Explanation:
Nothing would happen to the mass of the objects.
The mass of an object is constant.
However, the weight of the object depends on the gravitational attraction.
Weight is a force, and
f = mg
If g changes, then f changes.
Antias speed is about 17.142 km per hour.
60 divided by 3.5. The km divided by the hour gives the km per hour. Hope that helped :)
