Question

2. A Car of mass
of mass 1000 kg moving
with a velocity of 36kg comes to rest
5 sec. What is the exerted force
on the
in it​

Answer 1

Answer:

here is your answer

Explanation:

mass of car m= 1000 kg

velocity (initial speed ) U = 36km/h (by converting into m/s )

=36×5/18=10 m/s

final speed V=0

we know V=U +at

0= 10 +ax5

-10/5 =-2m/s retardation ( negative acceleration is known as retardation)

Force = mass x acceleration

force =1000×2 =2000 Newton
