A particle of mass 0.8 kg has acceleration (−3i+5j) m s−2(-3\mathbf{i}+5\mathbf{j})\text{ m s}^{-2}(−3i+5j) m s−2.
Find the resultant force acting on the particle.
Find the magnitude of the resultant force. Give your answer to 3 significant figures.
Find the angle between the resultant force and the positive i\mathbf{i}i direction. Give your answer to the nearest degree.
