Calculate acceleration of block and trolly system shown in figure. Coefficient of kinetic friction between trolly and the surface is 0.05, mass of string is negligible and no other friction exists

A

`1.50 m//s^(2)`

B

`1.66 m//s^(2)`

C

`1.00 m//s^(2)`

D

`1.25 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
D

`F_(g) = mu_(g)N`
= 5N
`a = (20-5)/12 = 1.25 m//s^(2)`
