"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"
