When work is done by an applied force, the objects energy will change. in this interactive, does the work cause a kinetic energy change or a potential energy change?

for context; the interactive is “It’s all Uphill”.

when work is done by an applied force, the objects energy will change. in this interactive, does the work cause a kinetic energy change or a potential energy change?

The work done cause the potential energy to change because the body was initially at rest before work done, it was after a force is applied that there is energy changes from potential to kinetic energy

Explanation:

increases it

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
