For what value of Fa will this 5 kg object accelerate at 1.5 m/s/s [Right]?

2.5 N

10 N

2 N

5 N

7. 5 N

The answer to your question is 10 N

Explanation:

Data

F = ?

mass = 5 kg

acceleration = 1.5 m/s²

Process

1.- I will start using the force of 10 N

-Calculate the resulting force

Fr = 10N + 3N - 3.5N - 2N

Fr = 13N - 5.5N

Fr = 7.5 N

2.- Calculate the acceleration using Newton's second law

-Formula

         a = F/m

-Substitution

         a = 7.5 N / 5 Kg

-Result

         a = 1.5 m/s²

This is the acceleration we were looking for so the answer is 10N to the right.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
