Question

Block B suddenly starts moving at an acceleration
6 m/s2. The mass of each block is same. The
coefficients of friction are shown. The displacement
of block B(in metre) relative to A in 2 seconds will
be (g = 10 m/sec2):
6m/sec?
B
U= 0.2
A
M= 0.05​

Answer 1

Answer:

A is block

Answer 2

Acceleration is the pace at which an element's engine speed varies in mechanics.

Gravitational acceleration is measured using vectors. The orientation of the net force applied to an object determines the orientation of its acceleration.

Assume the mass of the block is m and the mass of the plank is M.

4mmg=ma 4g=a 4a=4a=4a=4a=4a=4a=4 (0.2) mmg=ma mmg=ma mmg=ma mmg=ma mmg=ma mmg=ma (10) 2 m/sec a=42=2 m/sec a=42=2 m/sec a=42=2 m/sec a=42=2 m/sec a=42=2 m/sec a=42=2 m/sec

Using s=ut+ 2 1 at 2, we obtain u=0 m/sec and a=2 m/sec, u=0 a

(1) 2 s=0+ 2 s=0+ 2 s=0+ 2 s=0+ 2 s=0+ 2 s=0+ 2 s=0+ 2

As a result, B is the correct response.
