Question

Two cars are moving in the same direction.If the velocity of the first car is 55m/s and that of the second car is 40m/s, Calculate the relative velocity of the first car with respect to the second car. If they were moving in the opposite direction, what would be the relative velocity? Calculate

Answer 1

Step-by-step explanation:

Given

Two cars are moving in the same direction.If the velocity of the first car is 55m/s and that of the second car is 40m/s, Calculate the relative velocity of the first car with respect to the second car. If they were moving in the opposite direction, what would be the relative velocity? Calculate

Solution

Since the two cars are moving in the same direction with same speed therefore relative speed between two cars is zero.

Since the two cars are moving in the same direction with same speed therefore relative speed between two cars is zero.Let the relative speed of the third car be w.r.t the two cars.

Since the two cars are moving in the same direction with same speed therefore relative speed between two cars is zero.Let the relative speed of the third car be w.r.t the two cars.Relative velocity of the third car: 

$\tt\large\underline\purple{(4/60)h5km=75km/h}$

Actual velocity of the third car:75−30=45km/h
