What is the mass of cement block that requires a force of 200 N to accelerate it at 5 M's?

The mass of the cement block can be calculated using the formula F = ma, where F is the force, m is the mass, and a is the acceleration. Given: F = 200 N, a = 5 m/s^2. Rearranging the formula to solve for mass, we get m = F / a = 200 N / 5 m/s^2 = 40 kg. Therefore, the mass of the cement block is 40 kg.
