Question

1. what is the net force required to accelerate a 1250kg car at 7m/s²?

givens
unknown
equation
substitute
solve

Explanation:

Step1: Identify given values

Mass \(m = 1250\space kg\), acceleration \(a=7\space m/s^{2}\)

Step2: Identify unknown

Net force \(F\)

Step3: Write the equation

Newton's second law \(F = ma\)

Step4: Substitute values

\(F=(1250\space kg)\times(7\space m/s^{2})\)

Step5: Solve

\(F = 8750\space N\)

Answer:

Givens: \(m = 1250\space kg\), \(a = 7\space m/s^{2}\)

Unknown: \(F\)

Equation: \(F=ma\)

Substitute: \(F=(1250)(7)\)

Solve: \(F = 8750\space N\)
