The trajectory of an object is defined as x = (t-4)^2, what is the velocity at t = 5?(a) 2(b) 5(c) 1(d) 4I have been asked this question during an online interview.I need to ask this question from Straight Line Motion topic in portion Motion in a Straight Line of Physics – Class 11

Answer»

Right answer is (a) 2

To elaborate: The FUNCTION for velocity can be DERIVED by differentiating the equation with respect to t. v = 2(t-4) is the required function. When t = 5, v = 2(5-4) = 2.
