Question

if the net force on the dummy is 825 N towards the rear of the car, what is the dummy’s acceleration?

Answer 1

Given data

*The given mass of the dummy is m = 75 kg

*The given net force on the dummy is F_n = 825 N

The formula for the dummy's acceleration is given as

`a=(F_n)/(m)`

Substitute the known values in the above expression as

`\begin{gathered} a=(825)/(75) \\ =11m/s^2 \end{gathered}`

Hence, the dummy's acceleration is a = 11 m/s^2
