When you are in an elevator accelerating downward your apparent weight is: zero O less the same as when the elevator is at rest greater Question 5 (1 point) A person with a weight of 800 N, standing on an scale in an elevator which is moving upwards with a constant speed of 9.8 m/s will read a scale reading of: 1600 N 400 N 600 N 800 N

A large box is being pushed across the floor at a constant speed of 4.0 m/s. What can you conclude about the forces acting on the box? The amount of force applied to move the box at constant speed must be more than its weight The amount of force applied to move the box at constant speed must be more than the amount of the frictional forces that resist its motion O The amount of force applied to move the box at constant speed must be equal to the amount of frictional forces that resist its motion There is a force being applied to the box to make it move but the external forces such as friction are not "real" forces they just resist motion O If the force applied to the box is doubled, the constant speed of the box will double to 8.0 m/s

the rocket in a rocket powered airplane generates a steady force of 10,000 N in the foward direction and the plane moves horizontally at a constant velocity of 100 m/s through the air. The rocket engine is upgraded so that it now provides a foward force of 90,000 N. what is the new constant velocity of the plane> You cannot neglect air resistance in this question.  200 m/s 300m/s 400 m/s  600 m/s  900 m/s

In a vacuum, what is true of the acceleration of a 7 kg bowling ball and a 0.007 kg feather while in freefall? the bowling ball it depends on the air resistance the feather both objects will have the same acceleration     Two students are conducting an experiment in which they are trying to find a relationship between the angle of incline of a ramp and the final speed a car reaches when rolling down the ramp. In order to collect their data, the students must determine the final speed of the car at the bottom of the ramp. The students discuss how they should determine this speed. Student 1: “We need to measure the length of the ramp and the time it takes the car to roll down it. Then we can divide the total distance by the total time to find the final speed.” What is wrong with Student 1’s method for determining the final speed?   This method will only determine the average speed, not the final speed. This method will determine the acceleration, not the final speed.…

The tension in a string from which a 6.0-kg object is suspended in an elevator is equal to 44 N. What is the acceleration of the elevator?   Question 12 options:   14 m/s2 upward   15 m/s2 downward   11 m/s2 downward   2.4 m/s2 downward   12 m/s2 upward

#3 Hey! I’m confused on how to answer this problem, because I am unsure if there are multiple steps to follow in order to actually get the answer

The Earth pulls downward on a pingpong ball with a force  of 1N. If this is the "action" force, what is the "reaction" force? answer choices The ground exerts a force of 1N on the ping pong ball The ping pong ball exerts a force of 1 N on the Earth The ping pong ball pushes down on the earth with a force of 1N The is no reaction force when a gravitational force is involved

A person stands on a scale inside an elevator at rest (see the figure below). The scale reads W = 625 N. a W (a) What is the person's mass? kg (b) The elevator accelerates upward momentarily at the rate of a = 4 m/s?. What does the scale read then? N (c) The elevator then moves with a steady speed of 6 m/s. What does the scale read now?
