formula= W=f*d
w=work done
f=force
d=distance
w=f*d
w= 5n*0(does not budge)means does not move so distance is zero
w=5J
The work done by the children on the sumo wrestler is 5J
Answer:
Maximum velocity will be 17.651 m /sec
Explanation:
We have given a rope breaks when tension reaches 205 N
Mass m = 0.477 kg
Radius of the circle r = 0.725 m
Tension in the rope is given by




v = 17.651 m /sec
Answer: I think the answer is B. Potential energy
Explanation:
Because the higher the ball is held up the more energy it has.
I hoped I really helped out. ;)
A compound has a definite ratio of components
Answer: B
Explanation:
You can use the conservation of momentum, under the assumption that no mass was lost when the collision occurred. The initial momentum of the system must equal the final momentum of the system. Our system is the region including, and only including, the satellite and the space debris. Classical momentum is defined as the product of mass and velocity:


Due to mass 1 equaling mass 2, we can factor these quantities out:

Cancel the mass term on both sides to get:

We have the initial and final velocities for everything besides the final velocity of the satellite. Plug everything in:
