We obtain conditions for the nonexistence of global solutions and estimates of existence time for local solutions to the problem $$ \frac {d^ky}{dt^k} \ge a_1(t)|y|^{q_1}+a_2(t)|y|^{q_2}+\dots +a_n(t)|y|^{q_n}. $$ The proofs are based on the method of trial functions developed by Mitidieri and Pokhozhaev.
