The acceleration is 5 m/s^2.

Newton's 2nd Law gives us the formula that shows the relationship between force, mass, and acceleration. The common way to write the formula is

#F = m*a#

Solving that for acceleration yields

#a = F/m#

Plugging your data into that form of Newton's 2nd, we find that

#a = (75 N)/(15 kg) = 5 N/"kg" = 5 m/s^2#

I hope this helps,
