Prev
A Honda City car, a Maruti Alto car, a Tata Nano car, and a Mahindra Scorpio car, all are running at the same speed of 50 m/s under identical conditions. If all these cars are hit from behind with the same force and they continue to move forward, the maximum acceleration will be produced in:
a) Honda City: 1150 kg
b) Maruti Alto: 720 kg
c) Tata Nano: 600 kg
d) Mahindra Scorpio: 2510 kg
Answer:
The correct answer is c) Tata Nano: 600 kg

"hi guys welcome to lido q a video
i am vinit your little tutor excited to
bring this
long question on your screen a honda
city car
a maruti auto car a tata nano car
and a mahindra scorpio car all are
running at the same speed of 50 meter
per second
under identical conditions if all these
cars are hit from behind
with the same force and they continue to
move forward
the maximum acceleration will be
produced in
right now
let's see
when an
external force
causes change
in motion
right it is
opposed
by inertia
now inertia is directly proportional to
the
mass of a body right
therefore
higher the mass
higher the resistance
therefore the car with the
minimum weight will accelerate the
fastest
because the inertia will be the lowest
therefore
tata nano car will have the maximum
acceleration
isn't that easy guys if you have a doubt
though
please leave a comment below do like the
video and subscribe to our channel
i'll see you in our next video until
then bye guys keep learning"
