See the step by step solution

Step by Step Solution

Step 1: Content Introduction

Weight of an object is the gravitational force exerted on it and it is the product of the mass of the object m and the gravitational acceleration g.

The equation for the apparent weight of the passenger is

Here, a is acceleration of the passenger.

The expression which relates acceleration, velocity and time is

Step 2: Explanation (Part a)

The acceleration of passengers between time is

Substitute,

Step 3: Explanation (part b)

The acceleration of passenger at is zero.

The equation for apparent weight of the passenger at time is

Step 4: Explanation (Part c)

The acceleration of passenger at is

The equation for apparent weight of the passenger at time
