Short answer: 60°

Explanation: All inner angle of a triangle add up to 180° so 180° - 60° - 60° = 60°
Subtracting the 2 already given angels must be subtracted from 180° to know the final angle

Answer:

Step-by-step explanation:

All angles in a triangle have to add up to 180

60+ 60 + angle 3=180

120 + angle 3= 180

angle 3 = 60

A student pushes a 51.5 kilogram bookshelf across a smooth floor with a net force of 67 N.

iren [92.7K]

The acceleration of the bookshelf is equal to 1.30 $m/s^2$

Given the following data:

Mass of bookshelf = 51.5 kilogram

Net force = 67 Newton

To determine the acceleration of the bookshelf, we would apply Newton's Second Law of Motion:

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on the object while being inversely proportional to its mass.

Mathematically, Newton's Second Law of Motion is given by this formula;

$Acceleration = \frac{Net\;force}{Mass}$
