Question

question 14 of 24 grace pushes her foot against the wall with a force of 35 n while she stands on a skateboard. her mass, including the skateboard, is 55 kg. what is her rate of acceleration? a. 90 m/s² b. 1.6 m/s² c. 20 m/s² d. 0.64 m/s²

Explanation:

Step1: Apply Newton's second law

Newton's second law: \( F = ma \), so \( a = \frac{F}{m} \)

Step2: Substitute values

\( F = 35 \, \text{N} \), \( m = 55 \, \text{kg} \), so \( a = \frac{35}{55} \approx 0.64 \, \text{m/s}^2 \)

Answer:

D. 0.64 m/s²
