An ant crawls with a velocity on a turntable in the z, y plane that is turning with an angular speed ω in the counterclockwise direction.

(a) what is the rotation vector of the turntable?
(b) what is the vector describing the coriolis force if the ant is moving in the +r direction (in cylindrical polar coordinates) from a radius ro?
(c) what is the vector describing the coriolis force if the the ant moves tangentially to the turntable, that is, v=vф, from a radius ro?
(d) what is the vector describing the coriolis force if the the ant climbs vertically along a tube on the turntable, that is, v= vz, from a radius ro?

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them

explanation:

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

find the surface area of the sphere to the nearest square unit. use a calculator.
