During a test crash an airbag inflates to stop a dummies forward motion. the dummies mass is 75 kg. if the net force on the dummy is 825n toward the rear of the car what is the dummies deceleration

Dummies deceleration is 11m/s²

Explanation:

According to Newton's second law, the relationship between the force applied to an object, its mass, and the acceleration (or deceleration) caused, is given by:

Solving for acceleration:

If we plug in the vales (taking into account the negative sign of the force, as its directed backwards):

Deceleration is simply the magnitude of negative acceleration. Therefore, dummies deceleration is 11m/s²
