A car moves for 60s covering a distance of 3600m with zero initial velocity. What is the acceleration in m/s^2?(a) 2(b) 2.5(c) 3(d) 4.5I got this question in an interview for internship.This intriguing question originated from Kinematic Equations for Uniformly Accelerated Motion in chapter Motion in a Straight Line of Physics – Class 11

Answer»

Correct option is (a) 2

For EXPLANATION I WOULD say: Here we will use the second equation of motion, s = ut + (1/2)at^2. Here, u = 0, s = 3600, t = 60s. On SOLVING, we will GET a = 2 m/s^2.
