Answer:
self-maintained discharge
Explanation:
Answer:
26.4 m/s
Explanation:
4 g = 0.004 kg
By the law of momentum conservation, the momentum before and after the impact must be the same



So the speed of the block after the impact is 26.4 m/s
Work = Force x Distance
47.2J = 23.3N x d
d = 47.2/23.3
d = 2.0258 m
hope this helps :P
I think It would be C. Checking a prediction. Sorry if I’m wrong
3 is false 2 is true and the rest true
