Answer:

Explanation:
given,
radius of loop = 12.1 m
to find the minimum speed transverse by the rider to not to fall out upside down
centripetal force = 
gravitational force = m g
computing both the equation]





Answer:
24.4 m
Explanation:
first we have to calculate how long the cat will be in the air, in vertical direction this is free fall from 4m (poor cat, hope he survived) with acceleration of g=9.81 m/s^2
time = sqrt ( 2 * height / g)
time = sqrt (2 * 4 / 9.81)
time = 0,903 s
then we know his horizontal flight was 22 m long, so ve can calculate verical speed
speed = length / time
speed = 22 m / 0,903 s
speed = 24.363 m
as you are asked to give 3 significant numbers answer is 24,4 m
To find wave speed, you multiply the wavelength by the frequency. This means it is 8 times 11. This gives you 88. That means the answer is 88mm/s
Answer:
distance between Rome to Sorrento is 240 miles
Explanation:
given data
speed = 80 mph
time = 5 hours
reduce speed = 60 mph
to find out
distance between Rome to Sorrento
solution
let us consider time from Rome to Sorrento is x
we know 8 am to 8 pm total 12 hours and 5 hours in town spend so 12 -5 = 7
so we say that time back is 7 -x
we know distance was same
so distance is speed × time
compare both side distance
80 x = 60 (7-x)
80 x = 420 - 60 x
x = 3
so distance is = 80 (3) = 240 miles
distance between Rome to Sorrento is 240 miles
