To be honest I don’t know
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!
I did a project on Wood vs aluminum baseball bats to see which ball would travel farther when hit. I don't know If you play sports or anything but it was very fun for me considering I enjoy playing the game. You just got to be able to hit a ball with a bat
Answer:
2.75 m/s^2
Explanation:
The airplane's acceleration on the runway was 2.75 m/s^2
We can find the acceleration by using the equation: a = (v-u)/t
where a is acceleration, v is final velocity, u is initial velocity, and t is time.
In this case, v is 71 m/s, u is 0 m/s, and t is 26.1 s Therefore: a = (71-0)/26.1
a = 2.75 m/s^2
