There is at least one USCG-endorsed Class B-1 for the fire extinguisher that is required on any powerboat unless it is with the accompanying special case:
1. speedboats under 26 feet long,
2. moved by detachable engines and
3. not conveying travelers for procuring, require not convey such compact fire dousers if
4. the development of such speedboats won't allow the entanglement of touchy or combustible gasses or vapors
Before it reaches the ramp, the toy's kinetic energy is
(1/2) (mass) (speed²)
= (1/2) (3 kg) (16 m²/s²)
= 24 Joules .
On the way up the ramp, its kinetic energy will change to
gravitational potential energy, and it'll stop when it's height
gives it 24 joules of potential energy.
Potential energy = (mass) (gravity) (height)
24 joules = (3 kg) (9.8 m/s²) (height)
Divide each side by 29.4 kg-m/s² (that's the same as 29.4 newtons):
Height = 24 joules / 29.4 newtons
= 0.816 meter higher than the bottom of the ramp.
Answer: B
Explanation:
A machine multiplies the work output of a something by some amount. In this question, the ax is the machine. Thus, the ax is multiplying the work outputted by the lumberjack, so the answer is B. The reason it is not C is because there could be other forces interacting on the wood which the ax can affect.

- Evaporation
- Condensation
- Precipitation

Answer:
Distance covered is: 45 meters
Displacement is 15 meters to the right of where he started
Explanation:
Notice that Brady has walk a path that looks like an incomplete rectangle of height 5 meters and length 25meters, although he actually didn't cover the full length (25 meters) when getting back to the point where he started (he made just 10 meters instead of 25 after the third turn right) See attached image.
Therefore, Brady's displacement is 15 meters to the right of where he started, and the total distance he covered is :
Distance = 5m + 25m + 5m + 10m = 45m
