Question

when a car is moving with velocity 60 km\hr with 80km\hr in the same direction find the relative motion of a car.​

Answer 1

Solution :

Here,

<br>

<br>

<br> Velocity of (A) value of

indicates that the person sitting in car (B) sees car (A) moving ahead from him at the rate of

. <br> Velocity of (B) respect to

=v_(B) -v_(A)

=10 -(50)/3 =- (20)/3 =- 6. 67 ms^(-1)

v_(BA)

6.67 ms^(-1)

Answer 2

Answer:

The relative motion of the car is 20 km/hr.

Explanation:

Given:

• Velocity of the 1st car = 60 km/hr

• Velocity of the 2nd car = 80 km/hr

To find:

• Relative motion (velocity) of the car

Method to find:

Relative motion is the calculation of the motion of an object with regard to some other moving or stationary object.

Since they are travelling in the same direction, the relative motion of the car will be:

Relative velocity = Difference of the 2 speeds

⇒ Relative velocity = 80 - 60

⇒ Relative velocity = 20 km/hr
