A block of mass 500 g is at rest on a horizontal table. What steady force is required to give the block a velocity of `200"cms"^(-1)" in 4 s ?"`

Text Solution

AI Generated Solution

To solve the problem step by step, we will follow these steps: ### Step 1: Convert the mass into kilograms The mass of the block is given as 500 g. We need to convert this into kilograms because the standard unit of mass in physics is kilograms (kg). \[ \text{Mass (m)} = 500 \text{ g} = \frac{500}{1000} \text{ kg} = 0.5 \text{ kg} \] ...
