When you weigh yourself on good old terra firma (solid ground), your weight is 160lb . In an elevator your apparent weight is 140lb. What is the magnitude of the elevators acceleration.
Homework Equations
For this problem would we use the equation Fn= mg+ma

The magnitude of acceleration refers to the measurement of how much an object's velocity changes over time. It is usually measured in meters per second squared (m/s²) in the metric system or feet per second squared (ft/s²) in the imperial system.
The magnitude of acceleration can be calculated by dividing the change in velocity (final velocity - initial velocity) by the change in time. This is represented by the formula: a = (vf - vi) / t, where "a" is acceleration, "vf" is final velocity, "vi" is initial velocity, and "t" is time.
The magnitude of acceleration can be affected by various factors such as the force applied to the object, the mass of the object, and any resistance or friction present. The direction of the acceleration also plays a role as it can either increase or decrease the overall magnitude.
Velocity refers to the speed and direction of an object's motion, while magnitude of acceleration refers to the rate of change of an object's velocity. In other words, velocity tells us the object's current state of motion, while magnitude of acceleration tells us how much that motion is changing.
Measuring the magnitude of acceleration is important in understanding an object's motion and how it changes over time. It is also crucial in engineering and designing systems that involve motion, such as elevators, cars, or planes, as it allows for the calculation of necessary forces and adjustments to ensure safe and efficient movement.
