1.A crate with a mass of 15 kg is being dragged across the ground at a constant velocity of 2.0 m/s by an applied horizontal force of 30 N. (a) Name the other horizontal force acting on the crate. What is the magnitude and direction of that force? (b) How much applied force is required in order to accelerate the crate from a speed of 2.0 m/s to 7.0 m/s in 4.0 s?
