A physics student weighing 500 N stands on a scale in an elevator and records the scale reading over time. The data is
shown in the graph above. At time t= 0, the elevator is at rest on the ground floor.

What is the acceleration of the student
from 10-15 s?

Ann walks 80 meters on a straight line 33 ∘ north of east starting at point 1. draw ann's path. represent ann's walk with a vector of length 80 meters. draw the vector starting at point 1. the length given in the display is in meters.

The amount of potential energy possessed by an elevated object is equal to what?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
