Out of 500 car owners investigated, 400 owned car A and 200 owned car B, 50 owned both A and B cars. Is this data correct?

Out of 500 car drivers, 400 are the owners of Maruti and 200 are the owners of Hundai. If 50 are the owners of both, then find the whether the datas are correct or not ?

Fig. 2.40 ahead represents the displacement-time sketch of motion of two cars A and B. Find :(i) the distance by which the car B was initially ahead of car A. (ii) the velocities of car A and car B. (iii) the time in which car A catches car B. (iv) the distance from start when the car A will catch the car B.

Two cars a and B starts motion with a velocity of 10 m//s and 20 m//s respectively. Car a moves with a constant acceleration of 2.5 m//s^(2) and car B have constant acceleration of 0.5 m//s^(2) as shown in figure. Find when car A will over take car B. Dimension of car is negligible as compare to distance. Find the time after which car A over takes car B.

In a certain town, 25% families own a phone and 15% own a car, 65% families own neither a phone nor a car. 2000 families own both a car and a phone, then

In a certain town 25% families own a phone and 15% own a car, 65% families own neither a phone nor a car, 2000 families own both a car and a phone . How many families live in the town ?

Two cars A and B are moving on parallel roads in the same direction. Car A moves with constant velocity 30m//s and car B moves with constant acceleration 2.5 m//s^(2) . At , car A is ahead of car B and car B is moving with 12 m//s velocity . The distance travelled by car B until it overtakes car A is

Car A and car B move on a straight road and their velocity versus time graph are as shown in figure. Comparing the motion or car A in between t=0 to t =8 sec . And motion of car B in between t=0 to t=7 sec ., pick up the correct statement. .

An automobile engine propels a 1000 kg car (A) along a levelled road at a speed of 36 km//h. Find the power if the opposing frictional force is 100 N Now, suppose after travelling a distance of 200 m, this car collides with another stationary car (B) of same mass and comes to rest. Let its engine also stop at the same time. Now car (B) starts moving on the same level road without getting its engine started. Find the speed of the car (B) just after the collision.

A car moves at a constant speed on a road as shown in figure. The normal force by the road on the car is N_A and N_B when it is at the points A and B respectively .

Two car garages have a common gate which needs to open automatically when a car enters either of the garages or cars enter both. Devise a circuit that resembles this situation using diodes for the situation .
