Open in App

Solution

The displacement of the car from the initial position is

$D = \sqrt{S_{1}^{2} + S^{2}}$

$= \sqrt{3600 + 900}$

Displacement is $30 \sqrt{5} k m$

Two cars starf simultaneously from the same place and in same direction . The first car moves with a uniform speed of 10 km/h . The second car moves at a speed of 8km/hr in the first hour and then increases its speed by 0.5 km/hr in each succeeding hour . If both the cars move non stop , then how long will it take for the second car to overtake?
