Answer 1

See below

Step-by-step explanation:

See the attached file for the table answers.

Problem 1:

Find the mass with F=ma, where a is acceleration due to gravity (9.8 m/s^2). 1 Newton is defined as 1 kg*m/s^2.

25N = m*(9.8 m/s^2)

m = (25 kg*m/s^2)/(9.8 m/s^2)

m = 2.55 kg

Since there is no acceleration, Fr = Fa and net acceleration is 0.

Problem 2

F = ma

a = F/m

a = (2 kg*m/s^2)/2.6kg

a = 0.77 m/s^2

========================

Friction Coefficients

f = uN where f is friction force, u is the coefficient of friction, and N is the normal force.

1) -3N = u*(3N)

u = -1

2) -3N = u*(5N)

u = (-3/5) or -0.6

F = ma

a = F/m

a = (2 kg*m/s^2)/2.6kg

a = 0.77 m/s^2
