An object travels along a straight, horizontal surface with an initial speed of 2 ms. The position of the object as a function o
f time is given in the table. Which of the following graphs represents the object’s velocity as a function of time?
1 answer:
Answer:
The options are not provided, so i will answer in a general way.
We know that:
The movement is along a straight horizontal surface, then we have one-dimensional motion.
The speed is 2m/s
We want a graph of position vs time.
Now, remember the relation:
Distance = Speed*Time
Then we can write the position as a function of time as:
P(t) = 2m/s*t + P0
Where t is our variable, that represents time in seconds, and P0 is the position at time t = 0seconds, we can assume that this is zero.
Then the equation is:
P(t) = 2m/s*t
And the graph is something like:

Given
angular velocity
Combined moment of inertia of stool,student and bricks
Now student pull off his hands so as to increase its speed to suppose rev/s
After Pulling off hands so final moment of inertia is
Conserving angular momentum as no external torque is applied
Answer
given,
mass of glider = 0.23 Kg
spring constant = k = 4.50 N/m
spring stretched to 0.130 m
The springs potential energy =
U = 0.038 J
at x = 0,the only energy will be kinetic .
v² = 0.3304
v = 0.575 m/s
displacement of the glider
using conservation of energy
x = 0.678 m
