which flow diagram best explains the energy transformations that occur within an automobile running on diesel?
a) chemical energy → kinetic energy→ heat energy
b) heat energy → kinetic energy → chemical energy
c) kinetic energy → mechanical energy → heat energy
d) mechanical energy → heat energy → chemical energy

mechanical energy to heat energy to chemical energy

the part of the wave he is travelling on is the crest

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
