Question
A particle moves according to the equation; x = 10t2,where x is in meters and t is in seconds. Find the velocity forthe time interval from 2.0 s to 2.1 s
Solution
The velocity of a particle is given by the derivative of the position function. In this case, the position function is x = 10t^2.
Step 1: Differentiate the position function to get the velocity function. The derivative of 10t^2 is 20t. So, the velocity function is v(t) = 20t.
Step 2: Substitute the given time values into the velocity function to find the velocity at those times.
At t = 2.0 s, v(2.0) = 202.0 = 40 m/s. At t = 2.1 s, v(2.1) = 202.1 = 42 m/s.
So, the velocity of the particle increases from 40 m/s to 42 m/s in the time interval from 2.0 s to 2.1 s.
