- Hello! I’m on this worksheet that’s talking about Newton’s Second Law. Can someone please help me understand this question and what it is asking me to do in order for me to solve it?Draw the free-body diagram of the block. Using this diagram and your knowledge about Newton’s laws of motion, explain why is it that with 0.5 coefficient of friction, the minimum force required to move a 0.8kg-block is 3.8 N?Please answer it short and simple, but in an easy to understand way. What happens to the motion of the object when there is very little friction present? What did the surface look like? (hint: think: Ffr = ?Fn) What happens to the motion of the object when there is lots of friction present? What did the surface look like? What happens to the motion of the object when there is no friction present What did the surface look like?

Teacher hasn't returned my work on this yet, and we're having a quiz on Monday. A 2.75-kg cat moves in a straight line (x-axis).

And part B, we need to show the acceleration is inversely proportional to the mass, and the acceleration is directly proportional to the product of Force and one over mass. This is my data.
- Answer each question below using Newton’s second law. Explain your answers. (a) Two cars have the same net force acting on them, but one has more mass than the other.Which car will have the greater acceleration? (b) A heavy box of sand is on top of a cart. A person pulls the cart forward with a constant netforce while the sand leaks out of the box and onto the ground. What will happen to theacceleration of the cart?Solve the problem and answer the questions that follow. Would the force required to get the mass to start moving up the ramp be higher or lower than the force you calculated in the problem above? ______________________________________________________________________________ • Would the force required to keep the mass moving up the ramp be higher or lower than the force required to get the mass to start moving up the ramp? Why?A mover pushes a large packing crate across the floor in a straight line at a constant speed. What is the type of friction acting on the crate? kinetic ✓ Correct. 1-Because the crate is in motion, the type of friction exhibited in this case is kinetic friction. If the mover is applying a horizontal force of 110 N, what is the magnitude (in N) of the friction force on the crate? ⨯ Think about Newton's second law. If the velocity is constant, what's the acceleration? What's the net force? From this, if the mover pushes with a force in one direction, what must be the magnitude of the kinetic friction force in the other direction? N A large safe sits on a concrete floor. You push the safe horizontally, but the crate does not move. What type of friction force acts on the safe? static ✓ Correct. 2-Because the safe is motionless, the type of friction exhibited in this case is static friction. If the horizontal force you apply to the stationary safe above is 130 N, what is the…
