The acceleration of the object if the net force is decreased = 0.13 m/s²

<h3>Further explanation</h3>

Given

A net force of 0.8 N acting on a 1.5-kg mass.

The net force is decreased to 0.2 N

Required

The acceleration of the object if the net force is decreased

Solution

Newton's 2nd law :

\tt \sum F=m.a

The mass used in state 1 and 2 remains the same, at 1.5 kg

  • state 1

ΣF=0.8 N

m=1.5 kg

The acceleration, a:

\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{0.8}{1.5}\\\\a=0.53`m/s^2

  • state 2

ΣF=0.2 N

m=1.5 kg

The acceleration, a:

\tt a=\dfrac{\sum F}{m}\\\\a=\dfrac{0.2}{1.5}\\\\a=0.13~m/s^2

A whale travels 112 meters at 14 m/s How long does this take?
Anuta_ua [19.1K]
8 seconds, because if you use the formula distance divided by speed it would give you the time. So, if you divide 112 by 14 your answer would be 8. Hope this helped. Mark as brainliest if you can pls?

What is the potential energy of a 3 kilogram-ball that is on the ground?
Genrish500 [490]
The answer is 0
potential energy= mass• gravity (9.8m/s)• height. 
Your mass 3kg. I believe your need to convert this to grams (3000g) and then multiply by 9.8. Since your height is 0 because the ball is on the ground.your potential energy is 0.  hope that helped
