Answer :
use Force=Mass x Acceleration (newtons second law states force is directly proportional to the acceleration) so you can say that the force is negative and solve for Acceleration.
Answer:
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:
[tex]F=ma[/tex]
Solving for acceleration:
[tex]a=\frac{F}{m}[/tex]
If we plug in the vales (taking into account the negative sign of the force, as its directed backwards):
[tex]a=\frac{-825N}{75kg}=-11m/s^2[/tex]
[tex]a=-11m/s^2[/tex]
Deceleration is simply the magnitude of negative acceleration. Therefore, dummies deceleration is 11m/s²
