Answer 1

$\huge\star\underline\mathfrak\red{Answer:-}$

Given:

m= 1500kg

v = 0m/s

a = -1.7m/s

From newton's second law of motion,

Force = mass × acceleration

= 1500×(-1.7)

= -2550N

Hence, the force between the automobile and the road is -2550 N, in the direction opposite to the motion of the automobile.
