Question

Same  force act on objects of masses 1kg, 2kg and 3 kg. Which one has more acceleration ?​

Answer 1

For block A, F=M

T

a where a, acceleration of the system and M

T

is total mass of the system.

a=

3+2+1

12

=2m/s

2

Consider block B, the contact force between 2kg and 1 kg is T

c

=1a=2N
