WILL MARK BRANIEST: If the magnitude of the block's acceleration is 1.5 m/s2, what is the mass of the block? Show your work. (This is using the block from #22).

F = 0.84 [N]

Explanation:

In order to solve this problem we must take into account Newton's second law, which tells us that the sum of all forces applied on a body must be equal to the product of the mass of the body by its acceleration.

F = m*a

where:

F = force [N]

a = acceleration = 1.4[m/s^2]

m = mass = 0.6 [kg]

F = 0.6*1.4

F = 0.84 [N]
