Question

a toddler with a mass of 15 kg is able to generate 110 n of force to move herself forwards. what is her acceleration?
a) 9.8 m/s²
b) 7.3 m/s²
c) 1650 m/s²
d) 6.8 m/s²

Explanation:

Step1: Recall Newton's second law

$F = ma$, where $F$ is force, $m$ is mass, and $a$ is acceleration. We need to solve for $a$.

Step2: Rearrange the formula for acceleration

$a=\frac{F}{m}$

Step3: Substitute given values

Given $F = 110\ N$ and $m=15\ kg$, then $a=\frac{110}{15}\approx7.3\ m/s^{2}$

Answer:

B. 7.3 m/s²
