Question
If both the blocked as shown in the given arrangement are given together a horizontal velocity towards right. If acm be the subsequent acceleration of the centre of mass of the system of blocks then acm equals
Options
A.0 m/s2
B.
m/s2
m/s2C.
m/s2
m/s2D.2 m/s2
Solution
acm = 
= 2 m/s-2
OR
Acceleration of 1 kg w.r.t ground = (0.1)(10) = 1ms-2
Acceleration pf 2 kg w.r.t ground =
= ms-2
acm =
= 2 m/s-2
= 2 m/s-2OR
Acceleration of 1 kg w.r.t ground = (0.1)(10) = 1ms-2
