A car accelerates uniformly from rest to a speed of 72 km/h in 10 seconds. What is the distance covered during this time?

Question

Team JKSSB Mock Tests · Accepted Answer

First, convert speed to SI units: 72 km/h = 72 × (5/18) m/s = 20 m/s. Initial velocity (u) = 0, final velocity (v) = 20 m/s, time (t) = 10 s. Acceleration (a) = (v-u)/t = 20/10 = 2 m/s². Distance (s) = ut + (1/2)at² = 0 + 0.5 × 2 × 10² = 100 meters.
