Answer:
<u>Average Velocity:</u>
When a body covers some displacement moving from point A to B, in a given time,t. Then dividing the total distance covered by the time taken to complete the displacement is called as the average velocity of that car.
We can calculate the average velocity of car by subtracting the initial displacement of a body,s₁ from the final displacement position of the body, s₂. And then dividing by the initial time,t₁ been subtracted from the final time,t₂.
We will get the required results, now if we want to obtain the results in the final three seconds then, we can have the following explanation to that as given.
Explanation:
Lets say, that we have the car moving for 10 seconds and then it stops at the eleventh second of the trip on final position, of the displacement. Then we divide the whole trips into small segments, as we will have the different velocity at each interval but, the velocity is unknown at the last 3 seconds is unknown=?.
- Total time taken, Δt= 11 seconds,
- Then lets say the velocity at the 8th second is , v=25 m/s,then
- Δv=x₂-(25)/11-0,⇒Δv=x₂-25/11,
Answer:
ur 2 sqyares out of the cicle. how many squares to get back in for example.
Explanation:
Answer:
The acceleration of the object is 
.
Explanation:
Given that,
Mass of the block, m = 2.6 kg
Spring constant of the spring, k = 126 N/m
At the instant when the displacement of the spring from its unstained length is 0.115 m. We need to find the acceleration of the object.
When the block is displaced, the force acting on the spring is equal to the force due to its motion. Such as :
a is acceleration of the object
So, the acceleration of the object is .
