Two photographers are competing for business in town. andrea uses only film photography and
keira uses only digital photography. keira claims that the digital technology is superior, and her
advertisement claims that the images can be stored, shared, and copied more easily. they can
even be sent long distances using a series of wave pulses to transmit the information. andrea
replies that digital images can be stolen and altered more easily.

do the advantages outweigh the disadvantages, or do both sides have valid points? support
your answer with at least three reasons.

b. lifting dumbbell weight at 20-degree angle from the body after a 45-degree angle

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
