Force Concept(Test 1) Force Concept (Test 1) 1 / 10A block of mass 2 kg is placed on a frictionless surface. A force of 10 N is applied. What is the acceleration of the block? 2 m/s² 5 m/s² 10 m/s² 20 m/s² 2 / 10A 5 kg block is pulled with a force of 25 N on a rough surface. If the frictional force is 5 N, what is the acceleration? 4 m/s² 5 m/s² 6 m/s² 3 m/s² 3 / 10A block slides down a smooth incline of angle 30°. What is its acceleration? g g/2 g/√2 g/3 4 / 10A block of mass 10 kg is hanging from a rope. What is the tension in the rope if the block is at rest? 100 N 10 N 0 N 50 N 5 / 10Two blocks of masses 3 kg and 2 kg are connected and pulled with a force of 20 N. What is the acceleration of the system (frictionless)? 4 m/s² 5 m/s² 6 m/s² 2 m/s² 6 / 10A block of mass 4 kg is placed on a rough surface. Coefficient of static friction is 0.5. What is the maximum static friction? 10 N 20 N 40 N 0 N 7 / 10A block is moving with constant velocity on a rough surface. What is the net force acting on it? Zero Equal to friction Greater than friction Less than friction 8 / 10A block of mass 2 kg is placed on a frictionless incline of angle 60°. What is the normal force? 10 N 20 N 0N 2g cos(60) 9 / 10A block of mass 5 kg is acted upon by two forces: 15 N right and 5 N left. What is the net force? 10 N 20N 5 N 0 N 10 / 10A block of mass 3 kg is suspended and accelerating upward at 2 m/s².
