Question

question 5 (1 point) force was defined in section 3.10 as a push or a pull that acts on an object in order to make the object move or to make it move faster or slower. in other words, a force causes an object to accelerate (f = m*a). question 6 (1 point) a block of wood has a mass of 1.25 kg. how much force does it exert on the ground? the normal force is mass (kg) multiplied by the acceleration due to gravity (g), where g = 9.8 m/s²? a 12.25 n. b 12n c 1.25n d 9.8m/s

Explanation:

Step1: Recall the formula for normal force

The normal force \(N\) on a horizontal surface is \(N = mg\), where \(m\) is mass and \(g\) is acceleration due to gravity.

Step2: Substitute the given values

Given \(m = 1.25\ kg\) and \(g=9.8\ m/s^{2}\). Then \(N=(1.25\ kg)\times(9.8\ m/s^{2})\).

Step3: Calculate the result

\(N = 12.25\ N\)

Answer:

a. 12.25N
