A very dedicated physics student decides to ride the elevator in Strode while standing on a scale. The student weighs 700 N. Determine the apparent weight the student reads on the scale for the following 3 situations:a. The elevator is accelerating upwards at 3 m/s^2.b. The elevator is moving upwards at 7 m/s. c. The elevator is accelerating downwards at 4 m/s^2. Please include known values, a diagram, and implied values so I can better understand.

Can you please answer these. In the previous question the acceleration was found to be a= 1.675 Question 5 The situation for this problem is as explained in question 4. Block E is moving up and to the left (and Block D is moving down). The mass of Block D is 3.2 kg. The mass of Block E is 2.4 kg. The coefficient of kinetic friction between Block E and the plane is 0.5. The inclined plane is inclined at an angle of θ = 32 degrees above horizontal. Calculate the tension in the string (in units of newtons). Question 7 This question is the same as question 5 with the exceptions that The numbers have changed, and Block E is moving down and to the right (this refers to velocity) Block E is moving down and to the right (and Block D is moving up). The mass of Block D is 2.9 kg. The mass of Block E is 3.9 kg. The coefficient of kinetic friction between Block E and the plane is 0.41. The inclined plane is inclined at an angle of θ = 31 degrees above horizontal. Calculate the acceleration of…
A person pushes a box along the ground. The box has the force diagram shown below. Examine the force diagram to answer the following questions: a. Is the box in equilibrium? If so explain how you can tell. If not, explain why not. b. If the person wants the box to move at constant velocity, should they adjust their pushing on the block? If so, explain how they should change their push. If not, explain why they should change nothing about their push

A 10 N force is applied to a 4.0 kg block at rest on a table. The block experiences a frictional force. Draw a free-body diagram of the block. What is the weight of the block? What is the normal force on the block? If the coefficient of kinetic friction is µk = 0.20, what is the kinetic frictional force on the block? What is the net force on the block? What is the acceleration of the block from the net force? Just 1, 2, and 3 please!
Please see the image provided for context and solve the following problem: Solve for and use the magnitude of the force of friction on Debbie and the tension in the rope to solve the problem. The bruin is hungrier than Sarita anticipated, and she decided she needs to pull harder, accelerating Debbie up the rocky slope. Sarita's rope can only manage a tension of 950N. What is the maximum acceleration Sarita can accomplish with this rope?
