Question

A car travelling at 69 km/h overtakes another car travelling at 33km/h. Assuming each car to be 5.0m long ,find the time taken during the overtake in Seconds.
​

Answer 1

Explanation:

A car travelling ast 60 km/h overtakes another car travellign at 42 km/h. Assuming each car to be 5.0 m long, find the time taken during the overtake aned the total road distance used for the overtake. =s+5=33.3+5

I hope this is helpful to you

Answer 2

$\bigstar\huge\underline{\mathtt{Solution :}}$

Initial velocity of the car = 69 km /hr

In order to convert this into m /s multiply by 5 / 18

• Initial velocity = 69 × 5 / 18 = 19.16 m/s

Final velocity of the car = 33 km /hr

In order to convert this into m /s multiply by 5 / 18

• Final velocity = 33 × 5 / 18 = 9.16 m/s

Relative velocity of the car

= 19.16 - 9.16

= 10 m /s

• Length of each car = 5m
• Distance traveled by the car 1 when it overtakes car 2 = 5 + 5 = 10

Time taken by the car 1 to overtake car 2

= Distance / Relative velocity

= 10 / 10

= 1 sec

Time taken by car 1 to overtake car 2 = 1 sec
