A person stands on a scale inside an elevator at rest. The scale reads 800 N. The elevator accelerates upward  at the rate of 2.7m/s2 . What does the scale read then? Calculate answer to one decimal. ( use g = 9.8 m/s2 )

Consider a person standing on a scale in an elevator. If the elevator accelerates upwards with an acceleration of 1.27 m/s2 and the person has a mass of 79.2 kg, what would the scale read? HINT: you need to take into account the acceleration due to gravity, as well as that of the elevator.

A 60.8 kg person is standing inside an elevator. The elevator is moving upward at 3.49 m/s and is decreasing speed at a rate of 1.25 m/s^2. What is the force of gravity that is acting on the person?

A skydiver weighing 203 lbf (including equipment) falls vertically downward from an altitude of 5000 ft and opens the parachute after 14 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is 0.77 |v| when the parachute is closed and 10 |v| when the parachute is open, where the velocity v is measured in ft/s. Use g = 32 ft/s². Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. v(14) = i (b) Find the distance fallen before the parachute opens. x (14) = i ft ft/s (c) What is the limiting velocity after the parachute opens? UL = i ft/s
