Question

question 10 of 10
a skateboarder is accelerating forward. how would his acceleration change if he had more mass?
a. his acceleration would stay the same.
b. his acceleration would increase.
c. his acceleration would decrease.
d. his acceleration would be zero.

Explanation:

Step1: Recall Newton's second law

$F = ma$, where $F$ is force, $m$ is mass and $a$ is acceleration. Rearranging for acceleration gives $a=\frac{F}{m}$.

Step2: Analyze mass - acceleration relationship

Assume the force $F$ remains constant. When the mass $m$ increases, according to the formula $a=\frac{F}{m}$, the value of $a$ (acceleration) will decrease.

Answer:

C. His acceleration would decrease.
