Answer 2

Answer:

Explanation:

Given data:

mass of vehicle=1500kg

Retardation=1.7m/{sec

2

Here we can define this negative acceleration as retardation,which state that body is accelerating in opposite direction of applied force.

from newton's 2

nd

law of motion

f=ma

where f is the frictional force actin between the vehicle and the road,which will always act opposite to the direction of motion of body.

f−ma=0

f=ma=1500×1.7=2550N
