Bullet of mass 0.05 kg is fired from a gun with velocity 700 m/s, find the momentum of the gun immediately after it's fired?
I used Momentum = mv = ? - Here I'm taking the direction of the bullet as positive.
If the gun is brought to rest in 1s by a horizontal force that rises uniformly from 0 to Z N, then falls uniformly back to 0 again, find the value of Z.
No idea how to start this really. Was thinking to try and find the average acceleration and then use , however the acceleration isn't constant, so this wouldn't work would it?
Would love it if someone could give me a little pointer on this?
Thanks in advance
