Question

A body travels some distance with a constant acceleration, then some distance with

constant velocity then comes to rest with constant retardation. Draw the velocity-time graph

and corresponding displacement-time graph.

Please answer it guys ​

Answer 1

Answer:

Q1

A particle accelerates from rest at a constant rate for some time and attains a constant velocity of 8ms−1. Afterwards it decelerates with a constant rate and comes to rest. If the total time is 4 second, the distance traveled is:

Q2

A lift ascends with constant acceleration f, then with constant velocity, and finally stops under constant retardation f. If the total distance ascended is s and total time occupied is t, then time during which the lift ascended with constant velocity is

Q3

A particle stars from rest covers a distance of x with constant acceleration then move with constant velocity and cover distance 2x then after come to rest will constant retardation with cover distance of 3x, then ratio of Vmax/Vavg will be
