A 15-kg bоx is being pushed аlоng а hоrizontаl surface. The pushing force is directed at an angle of 15° below the horizontal. The coefficient of static friction between the box and the ground is 0.65, and the coefficient of kinetic friction is 0.35. What horizontal force must be exerted on the box for it to accelerate at 1.2 m/s2?
