Answer:
infrared, visible and ultraviolet regions.
Explanation:
The position of the object at time t =2.0 s is <u>6.4 m.</u>
Velocity vₓ of a body is the rate at which the position x of the object changes with time.
Therefore,
Write an equation for x.
Substitute the equation for vₓ =2t² in the integral.
Here, the constant of integration is C and it is determined by applying initial conditions.
When t =0, x = 1. 1m
Substitute 2.0s for t.
The position of the particle at t =2.0 s is <u>6.4m</u>
The difference between the distance and the displacement is the speed is a scalar while displacement is a vector.
<h3>What is the distance an the displacement?</h3>
The distance is the difference between two points while the displacement is the difference between two points in a specified direction. Given that speed is a scalar and the displacement is a vector. It follows that we must take the displacement when obtaining the displacement.
Thus, the distance that is covered after one lap is the circumference of the circle = 2πr = 2 * 3.142 * 25 = 31 m Then for 2 laps = 62 m
The displacement is obtained when we take the direction into consideration. Owing to the fact that the runner returns to the starting point each time, the displacement is zero.
