600ms I think
Explanation:
3*200
Answer:
from the above analysis we can say that the angular velocity in the later case is more than that of the former case. This means that the number of rotation made in the truck case is more than that made in pike position.
Explanation:
This can be explained on the basis of conservation of angular momentum.
This means the initial and the final angular velocity is conserved. Consider initial position (1)in the pike and final position in the be truck position. So there inertia's will also be different.
⇒

also,


since, 

therefore,

So, from the above analysis we can say that the angular velocity in the later case is more than that of the former case. This means that the number of rotation made in the truck case is more than that made in pike position.
Answer:
A
Explanation:
take note that v=d/t (velocity is distance over(divided by) time, so in this case it would be 200 (distance) divided by 2 (time)
Answer:
D. When the dense, positive alpha particle passes close to a positive nucleus of gold, the alpha particle repels and hits the screen at point X.
Explanation:
Answer with Explanation:
We are given that
Mass of bullet,




We have to find the velocity of the bullet and block B after the first impact and final velocity of the carrier.
According to law of conservation of momentum



Hence, the velocity of the bullet and block B after the first impact=4.65 m/s
According to law of conservation of momentum
