Anettt [7]

Answer:

The speed of the automobile after 1.43s is 10 $\frac{m}{s}$

Explanation:

$a= \frac{-f}{m}= \frac{-u_{k}*m*g}{m}$

$a= -u_{k}*g=- 0.590* 9.8 \frac{m}{s^{2} }= -5.782 \frac{m}{s^{2} }$

$V_{f} = V_{i} + a*t$

$V_{f} = 18.2 \frac{m}{s} - (5.782 \frac{m}{s^{2} }* 1.43 s)$

$V_{f} = 9.93174 \frac{m}{s}$

$V_{f}$ ≅ 10 $\frac{m}{s}$
