SUMMARY

The maximum speed of the elevator is calculated to be \( \frac{1}{4} \alpha t_0 \), where \( \alpha \) represents the acceleration coefficient and \( t_0 \) is the time duration of the elevator's motion. To find the total distance traveled by the elevator, the velocity function must be derived from the acceleration function \( a_y(t) = \alpha - 2\alpha \frac{t}{t_0} \). The correct integration of the velocity function over the interval from 0 to \( t_0 \) is necessary to obtain the total distance, which is not \( \frac{1}{4} \alpha t_0^2 \) as initially attempted.

PREREQUISITES
  • Understanding of kinematics, specifically motion under constant acceleration
  • Familiarity with calculus, particularly integration techniques
  • Knowledge of the relationship between acceleration, velocity, and displacement
  • Ability to manipulate algebraic expressions involving variables like \( \alpha \) and \( t_0 \)
NEXT STEPS
  • Learn how to derive the velocity function from an acceleration function
  • Study the principles of definite integrals in calculus for calculating displacement
  • Explore the concepts of motion in elevators and the forces acting on objects in non-inertial frames
  • Practice problems involving kinematic equations and integration to solidify understanding
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and kinematics, as well as educators looking for examples of motion analysis in elevators.

Homework Statement



A person of mass mp stands on a scale in an elevator of mass me . The scale reads the magnitude of the force F exerted on it from above in a downward direction. Starting at rest at t=0 the elevator moves upward, coming to rest again at time t=t_0. The downward acceleration of gravity is g . The acceleration of the elevator during this period is shown graphically above and is given analytically by ay(t)=α−2αt_0t

a) Find the maximum speed of the elevator. Express your answer in terms of α and t0

b) Find the total distance traveled by the elevator. Express your answer in terms of α and t0 (enter alpha for α and t_0 for t0)

Homework Equations





The Attempt at a Solution



I got part a right (answer is 1/4*alpha*t_0) but I don't know how to get b I tried integrating the velocity with repsect to t with the limits of t_0 and 0 and I got 1/4*a*t_0^2, but that is not right. Can someone please tell me what I;m doing wrong?
