Atruck with 0.410 m radius tires travels at 25.0 m/s. what is the angular velocity of the rotating tires in radians per second?

relation between linear velocity and angular velocity is given as

here

v = linear speed

R = radius

= angular speed

now plug in all data in the equation

so rotating speed is 60.9 rad/s

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
