Answer:
Fc=5253
N
Explanation:
sequel to the question given, this question would have taken precedence:
"The 86.0 kg pilot does not want the centripetal acceleration to exceed 6.23 times free-fall acceleration. a) Find the minimum radius of the plane’s path. Answer in units of m."
so we derive centripetal acceleration first
ac (centripetal acceleration) = v^2/r
make r the subject of the equation
r= v^2/ac
ac is 6.23*g which is 9.81
v is 101m/s
substituing the parameters into the equation, to get the radius
(101^2)/(6.23*9.81) = 167m
Now for part
( b) there are two forces namely, the centripetal and the weight of the pilot, but the seat is exerting the same force back due to newtons third law.
he net force that maintains circular motion exerted on the pilot by the seat belts, the friction against the seat, and so forth is the centripetal force.
Fc (Centripetal Force) = m*v^2/r
So (86kg* 101^2)/(167) =
Fc=5253
N
Answer:
- A vibrating object
- a medium to travel

Netiquette is a list of all acceptable acronyms when texting. Netiquette refers to etiquette, or protocols and norms for communication, on the Internet.
Kinetic energy has nothing to do with anything other than motion of the particle.
When a particle with velocity v collides another particle(suppose it is at rest for simplication), assuming that there is perfectly elastic collision between them, the velocity of particle which was at rest becomes mv/M ( assuming mass of particle in motion to be m and at rest to be M) from convervation of linear momentum. And all this transfer of energy happens in a fraction of seconds which is not visible to naked eyes.
Hence 1st option is correct!
The first thing you should do is calculate the work done when climbing the stairs. This work by definition will be given by:
W = F * d
W = (m * g) * (d)
W = ((71) * (9.8)) * (3) = 2087.4J
Then, you can calculate the power that in this case is given by
P = W / t
P = (2087.4) / (10) = 208.74W
To have the result in HP we use the fact that 1HP = 746W
P = (208.74) / (746)
P = 0.28 HP
answer
the power you produce in running up a flight of stairs is 0.28 HP
