Question

Troy, a 90 kg boy, pushes with a force of 5.0 N on a model of ambulance and gives the ambulance an acceleration of 2.00 m/s². What is the weight of the ambulance?

Answer 1

The weight of the ambulance is 24.5 N, as calculated using Newton's Second Law of Motion and the formula for weight.

Step-by-step explanation:

To find the weight of the ambulance, we first need to understand that weight is the force of gravity on an object and is calculated by the formula weight (W) = mass (m) × gravity (g), where gravity (g) is 9.8 m/s² on Earth. Since we know the force applied to the ambulance (5.0 N) and the acceleration it produced (2.00 m/s²), we can use Newton's Second Law of Motion (F = m × a) to calculate the ambulance's mass. Substituting the known values we get 5.0 N = m × 2.00 m/s², which gives us a mass (m) of 2.5 kg for the ambulance. Therefore, the weight of the ambulance is W = 2.5 kg × 9.8 m/s² = 24.5 N.
