The horizontal surface on which the block of mass 4 kg slides is frictionless. The force of 30N acts on the block in a horizontal direction and the force of 60N acts on the block at an angle. What is the magnitude of the resulting acceleration of the block? The acceleration of gravity is 9.8 m/s^2. Answer in m/s^2.
figure the hoizontal component of the 60 N force, add it to the 30N force, then
Net horizontal force= mass* acceleration
