An object has an acceleration of 18.0 m/s/s. If the net force was doubled and the mass were tripled then the new acceleration wo
kenny6666 [7]

Answer:

12.0 m/s²

Explanation:

Newton's second law:

F = ma

Solving for acceleration:

a = F/m

If force is doubled and mass is tripled:

a' = (2F)/(3m)

a' = ⅔ (F/m)

a' = ⅔ (18.0 m/s²)

a' = 12.0 m/s²

A child at the top of a slide de has a gravitational store of 1800J. What is the child's maximum kinetic store as he slides down
solmaris [256]
The maximum is 1800 J since energy is not created nor destroyed, it is just transformed. In this example, gravitational potential energy is transformed to kinetic energy.
