(a) $4.14 rad/s^2$

The relationship beween centripetal acceleration and angular speed is

$a=\omega^2 r$

where

$\omega$ is the angular speed

r is the radius of the circular path

Here we gave

$a = 9g = 88.2 m/s^2$ is the centripetal acceleration

r = 5.15 m is the radius

Solving for $\omega$ , we find:

$\omega = \sqrt{\frac{a}{r}}=\sqrt{\frac{88.2 m/s^2}{5.15 m}}=4.14 rad/s^2$

(b) 21.3 m/s

The relationship between the linear speed and the angular speed is

$v=\omega r$

where

v is the linear speed

$\omega$ is the angular speed

r is the radius of the circular path

In this problem we have

$\omega=4.14 rad/s$

r = 5.15 m

Solving the equation for v, we find

$v=(4.14 rad/s)(5.15 m)=21.3 m/s$

What is the potential energy of a 2kg object placed 6m above the surface of the Earth?

zalisa [80]

Answer:117.6joules

Explanation:

Mass(m)=2kg

Height(h)=6m

Acceleration due to gravity(g)=9.8m/s^2

Potential energy(PE)=?

PE=m x g x h

PE=2 x 9.8 x 6

PE=117.6joules

guapka [62]

The time taken to fill the vat can be found using the least common multiple [LCM]. Given that the first pipe fills the tank in 66 hours and the second one empty the tank in 1010 hours, the time taken to fill the tank will be:
LCM(66,1010)
=66*1010
=66,660 hours
the answer is:
66,660 hours
