What is the acceleration? 3 m/s² 6 m/s² 2 m/s² 9 m/s² 2 / 10A block of mass 10 kg is placed on an incline of 37°. Coefficient of friction is 0.2. What is the frictional force? 20 N 10 N 16 N 0 N 3 / 10A block of mass 2 kg is moving in a circular path of radius 1 m with speed 4 m/s. What is the centripetal force? 8 N 16 N 4 N 2 N 4 / 10A spring is stretched by 0.1 m and has a spring constant of 200 N/m. What is the force exerted by the spring? 20 N 200 N 2 N 0.2 N 5 / 10A block of mass 1 kg is moving with velocity 5 m/s. A force of 2 N is applied opposite to motion. How long to stop? 2.5 s 10 s 5 s 10 s 6 / 10A block of mass 3 kg is pushed against a wall with 60 N. Coefficient of static friction is 0.5. Will it stay? Yes No Moves slowly Not enough data 7 / 10A block of mass 2 kg is placed on a horizontal surface. A force of 5 N is applied at 60° above horizontal. What is the vertical component? 2.5 N 4.3 N 5 N 0 N 8 / 10A block of mass 4 kg is placed on a rough incline of 30°, μ = 0.4.
