A rod of length 0.82 m, rotating with an angular speed, 4.2 rad/s, about axes that pass perpendicularly through one end, has a m

vodomira [7]

Hi there!

$\large\boxed{KE =1.245 J}}$

The equation of angular kinetic energy is:

$KE = \frac{1}{2}Iw^2$

Where:

I = moment of inertia (kgm²/s)

ω = angular speed (rad/sec)

A rod rotated about one of its endpoints has a standard moment of inertia of 1/3mR², so:

$KE = \frac{1}{2}(\frac{1}{3}mL^2w^2)$

$KE = \frac{1}{6}mL^2w^2$

Plug in the given values:

$KE = \frac{1}{6}(0.63)(0.82^2)(4.2^2) = 1.245 J$

What average net force is required to accelerate a car with a mass of 1200 kg from rest to 27.0 m/s2 in 10.0 s ?

pogonyaev

Use formula F = MA
Acceleration= (27 m/s2)/10s = 2.7 m/s/s
F = 1200kg * 2.7 m/s/s = 3240 N
