Answer: 100 N

Explanation: Taking into account the second Newton Law the total force applied to any system is equal to the mass * acceleration. In this case the crate moves at constant speed so the accelaration is zero. In order to satisfy this fact, the friction force must be equal the applied force of 100 N.
