PRELAB QUESTIONS1. Looking down from a stationary tree branch, a merry-go-round spins in a counter-clock-wise direction with an angular velocity of 1 radian per second. A squirrel of mass 0.6kg sits on the outer rim of the merry-go-round, at a radius of 4.0meters. a)What is the magnitude and direction of the vector ?b) What is the magnitude and direction of the Coriolis pseudo-force as felt bythe squir-rel?c) What is the magnitude and direction of the centrifugal pseudo-force as felt bythe squirrel?

explanation:

its math

ill do it for 100, also this isnt 80 its 40

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
