Enter the three answers in their respective order without any commas or spaces between
letters.
a. Increase
b. Decrease
c. Remain the same
d. Nonsense! It is impossible to tell without more information.​

Respuesta :

Answer:

abd

Explanation:

As an object speeds up, its kinetic energy increases.

Object is moving horizontally so its potential energy remains same.

Because U is not negative and we don't know of energy being lost to the environment due to exterior forces, the mechanical energy K + U will increase.
