Explanation / Answer

both the forces are in perpendicular direction

so,

net force = sqrt(y force^2 + x force^2)

net force = sqrt(60^2 + 40^2)

net force = 72.11 N

force = mass * acceleration

72.11 = 6.2 * acceleration

acceleration = 72.11 / 6.2

acceleration = 11.63 m/s^2

direction = tan^-1(y force / x force)

direction = tan^-1(60 / 40)

direction = 56.31 degree
