- 3. A 4.0 kg block is sliding down a frictionless inclined plane as shown . What is the acceleration of the block? (A) 2.5m/s^2 (B) 5.5m/s^2 (C) 6.6m/s^2 (D) 8.1m/s^2
- 5. Are seismic waves (waves throughout the Earth's crusty mechanical waves? How about sound? Light (electromagnetic waves)? In each case , if the wave is a mechanical wave, identify the medium.
- The 5.0 kg box shown is at rest on the incline. What is the frictional force acting on the box? (A) ON (B) 5.0 N (C) 21 N (D) 49 N
- 1. A block is on a frictionless incline. Which is the correct free body diagram for the block? (A) (B) (C) (1) un Test A Inclines
- 5. Acceleration Calculation: A force of 60 N is applied to a 15 kg object. What is the acceleration of the object? 6. Net Force Direction An object is being acted upon by two forces: 25 N to the right and 10 N to the left. In which direction will the object move, and what is the net force? 7. Balanced Forces Example: Describe a real-life situation where balanced forces are acting on an object. Explain how you know the forces are balanced. 8. Unbalanced Forces Example: Provide a real-life example of unbalanced forces causing motion. Explain how the forces are unbalanced. 9. Mass and Acceleration If the same net force is applied to two objects of different masses,how will their accelerations compare? Explain using Newton's Second Law.
