Jason makes a graphic organizer for insulators and conductors and wants to add the following labels to it. label 1: lacks free electrons label 2: aluminum in which regions should jason place each label? a) label 1: x label 2: y b) label 1: z label 2: x c) label 1: x label 2: z d) label 1: z label 2: z

Jason should place the regions in:

C) Label 1: X

Label 2: Z

we need to know the time interval during which the force acts. impulse of force = momentum change

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
