The end of a horizontal rope is attached to a prong of an electrically driven tuning fork that vibrates at 100hz. the other end passes over a pulley and supports a 2-kg mass. the linear mass density of the rope is 0.075 kg/m. what is the wavelength of a transverse wave on the rope?

0.25 m
0.16 m
0.12 m
1.2 m

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
