Asled that has a mass of 8 kg is pulled at a 50 degree angle with a force of 20 n. the force of friction acting on the sled is 2.4 n. the free-body diagram shows the forces acting on the sled. what is the acceleration of the sled and the normal force acting on it, to the nearest tenth? 1) a = 1.3 m/s2; fn = 63.1 n 2) a = 1.6 m/s2; fn = 65.6 n 3) a = 1.9 m/s2; fn = 93.7 n 4) a = 2.2 m/s2; fn = 78.4 n
