Eli and Andy want to find out which of the two is stronger. Eli pushes a table with a force of 120 newtons while Andy pushes the table from the opposite side with a force of 125 newtons. Ignoring the masses of Eli and Andy, what is the resultant acceleration of the table if its mass is 10.0 kilograms?

A.
13.5 meters/second2
B.
0.50 meters/second2
C.
4.0 meters/second2
D.
5.50 meters/second2
E.
1.35 meters/seconds2

Answer:

B. 0.50 meters/second^2

Step-by-step explanation:

Given:

  • mass of table (m) = 10.0 kg
  • Eli's force (F1) = 120 N
  • Andy's force (F2) = -125 N

Arranging Formulas and Substituting Values, Part 1:

  • F = F1 + F2
  • F = 120 + (-125)
  • F = -5 N
  • The -5 means that the table will move along the direction of the force applied by Andy.

Arranging Formulas and Substituting Values, Part 2:

  • m * a = F
  • a = F / M
  • a = -5 / 10.0 kg
  • a = -0.5 m/s^2
