Answer 2

Answer:

a) Initial speed of the car is 10m/s

b) B to C part of the car shows 0 acceleration

c) C to D part of the car shows varying retardation

d) s=ut+½at² ( to find distance )

u=10 km/h

t= 8 hrs

a=v-u/t

=35-10/8

=25/8

=3.125 m/s²

distance:-

10×8+½×3.125×8²

80+½×3.125×64

80+3.125×32

80+100

180

Ans so the answer will be 180 m
