A truck of mass 8 ton is carrying a block of mass 2 ton. If a breaking force of 25 kN is applied on the truck, then the frictional force acting on the block is
(Coefficient of static friction between the block and the truck is 0.3 )
- A 6250 N
- B 6000 N
- C 5000 N
- D 1000 N
Answer & Solution
Correct Answer
(C) 5000 N
Step-by-step Solution
Detailed explanation
\( M_{total} = (8000 + 2000) \, \text{kg} = 10000 \, \text{kg} \) \( a = \frac{25000 \, \text{N}}{10000 \, \text{kg}} = 2.5 \, \text{m/s}^2 \) \( F_{required} = 2000 \, \text{kg} \times 2.5 \, \text{m/s}^2 = 5000 \, \text{N} \)…
