In one amusement park ride, riders enter a large vertical barrel and stand against the wall on its horizontal floor. the barrel is spun up and the floor drops away. riders feel as if they are pinned to the wall by a force something like the gravitational force. this is a fictitious force sensed and used by the riders to explain events in the rotating frame of reference of the barrel. explain in an inertial frame of reference (earth is nearly one) what pins the riders to the wall, and identify all of the real forces acting on them.

nah.   i'm just sleepy.

a straight line sloped

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

the inner core.

good luck: )
