Question

1. a 100kg person accelerates on their bicycle at a rate of 4m/s². calculate the net force. replace symbols with (correct) numbers do the math

Explanation:

Step1: Identify given values

Mass \( m = 100\ \text{kg}\), acceleration \( a=4\ \text{m/s}^2\)

Step2: Recall Newton's second law

\(F = ma\)

Step3: Substitute values

\(F=(100\ \text{kg})\times(4\ \text{m/s}^2)\)

Step4: Calculate

\(F = 400\ \text{N}\)

Answer:

Givens: \(m = 100\ \text{kg}, a = 4\ \text{m/s}^2\)
Unknown: \(F\) (net force)
Equation: \(F=ma\)
Substitute: \(F=(100\ \text{kg})\times(4\ \text{m/s}^2)\)
Solve: \(F = 400\ \text{N}\)
