Question

question 23 of 25
how much force is required (in newtons) to accelerate a 4 - kg skateboard, along with its 46 - kg rider, at 3 m/s²?
give your answer as a number.

Explanation:

Step1: Calculate total mass

Total mass \( m = 4\ \text{kg} + 46\ \text{kg} = 50\ \text{kg} \)

Step2: Apply Newton's second law

Force \( F = m \times a = 50\ \text{kg} \times 3\ \text{m/s}^2 = 150\ \text{N} \)

Answer:

150
