d. Newton's second law says that if the net force acting on an object is steadily decreasing, then the resulting acceleration will be (zero, constant, steadily increasing, steadily decreasing) 9. a. Consider a 10 kg block initially at rest on a horizontal frictionless surface. It is pushed with a force of 20 N to the right. Q: Sketch the problem Q: What is the net force in the vertical direction? Q: What is the net force in the horizontal direction? Q: What is the overall net force? Q: Will the block change its motion from rest (ie accelerate)? Explain Q: Calculate the block's acceleration. 10. a. Consider a 20 kg block initially at rest on a horizontal frictionless surface. It is pushed with a force of 20 N to the right. Q: Sketch the problem Q: What is the net force in the vertical direction? Q: What is the net force in the horizontal direction? Q: What is the overall net force? Q: Will the block change its motion from rest (ie accelerate)? Explain Q: Calculate the block's acceleration. Q: Compare the acceleration values in question #9 and #10. Why is it different when the net force is the same? Explain on the basis of Newton's second law 11. Four forces act on a 10 kg block initially at rest as shown. DON 120" WON HON Q: Explain Why the block will not remain at rest. Q: As a result of these forces explain why the block will NOT move with constant speed to the left Q: As a result of these forces explain why the block will NOT uniformly accelerate to the right Q: As a result of these forces explain why the block will NOT uniformly accelerate to the up Q: CalculatWe block
