The pulley system, shown in the figure, has two pulleys of radii 2 m and 1 m , respectively. If the acceleration of block A is 5 m s - 2 in the downward direction, then the acceleration of block B will be
Options
- A0   m   s - 2
- B5   m   s - 2
- C10   m   s - 2
- D5 2   m   s - 2
Correct answer
D. 5 2   m   s - 2
Step-by-step solution
Given a A = α × 2   m = 5   m   s - 2 ⇒ α = 5 2   m   s - 2 Hence, acceleration of B , a B = α × 1   m = 5 2   m   s - 2
