When little albert was conditioned to be afraid of the white mouse, he also became afraid of stuffed animals,
other furry things, and even santa claus. these learned behaviors demonstrated the phenomenon of
select one:
a. extinction x
b. stimulus discrimination
c. stimulus generalization
d. spontaneous recovery

newton's first law of motion

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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
