The 100 kg blcok in the figure takes 5.40 s to reach the floor after being released from rest. What is the mass of the block on the left?

2. Relevant equations

F=ma

s_{f}=s_{i}+ (1/2)(a)(delta t)

3. The attempt at a solution

I know to find acceleration you use

s_{f}=s_{i}+ (1/2)(a)(delta t)

0=1+(1/2)(a)(5.4)

a = 0.0686 m/s^{2}

and then the F=ma to find the force on the block of known mass.

F=(100 kg)(0.0686)

F=6.86

but from this I am not sure how to determine the mass of the block on the left?
