Answer:
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
