An apple crate with weight of 49N accelerates at 0.5m/s2 along a horizontal a force of 20N apllied above the horizontal at 19 degrees is required to bring the crate on the verge of motion. Find the coefficient of static friction between the crate and the surface.(adsbygoogle = window.adsbygoogle || []).push({});

-usn+20 cos 19 x direction

N+W+20 cos 19 y direction

F=ma F=5x0.5

F=2.5

don't know what to do next..please help
