A block of mass 1 kg lies on a horizontal surface in a truck. The coefficient of static friction between the block and the surface is 0.6. If the acceleration of the truck is `5m//s^2`, the frictional force acting on the block is…………newtons.

Explanation

To solve the problem step by step, we will follow these steps:

### Step 1: Identify the given data
- Mass of the block (m) = 1 kg
- Coefficient of static friction (μ) = 0.6
- Acceleration of the truck (a) = 5 m/s²
- Acceleration due to gravity (g) = 10 m/s² (assuming standard value)
