To solve the problem step by step, we will use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = m * a). ### Step 1: Calculate the acceleration in the first scenario We know that acceleration (a) can be calculated using the formula: \[ a = \frac{v - u}{t} \] where: ...
