Which would requires a greater force: accelerating a `2kg` mass at `5m//s^(2)` or a `4kg` mass at `2m//s^(2)`?

Text Solution

To determine which scenario requires a greater force, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). The formula is given by: \[ F = m \times a \] Let's analyze both scenarios step by step. ### Step 1: Calculate the force required for the first mass - **Given:** ...
