Question

the particle moves along x axis in such a way that its x co oridinate varies with time acc. to equation x= 4-2t+t^2. the speed of the particle will vary with time as

Answer 1

Heya......!!!

_______________________

Given in the question :

⇒ x = t² - 2t + 4

We know that speed is equal to. => $\frac{dx}{dt}$

⇒ $\frac{dx}{dt} ( t^2 - 2t + 4 ) = 2t - 2$

Speed of particle varies with time as :-

→ v = 2t - 2
