Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method: Places A and B are 100 km apart on a highway. One car starts from A and another from B at the same time. If the cars travel in the same direction at different speeds, they meet in 5 hours. If they travel towards each other, they meet in 1 hour. What are the speeds of the two cars?

In each of the following a force F is acting on an object of mass m. The direction of dispalcement is from west to east shown by the longer arrow. Observer the diagrams carefully and state whether the work done by the force is negative, positive or zero.

Car A of mass 1000 kg moves on a horizontal straight road with speed 36kmh^(-1) . If the force resisting the motion is 100 N, then find the power of the engine. Now, after covering 200 m distance, car A collides with a stationary car B of same mass and becomes stationary. As a result car B start moving on the horizontal road, then what would be the speed of car B just after the collision? (The engine of car B is off.)

Places A and B are 100 km apart from each other on a highway. A car starts from A and another from B at the same time. If they move in the same direction, they meet in 10 hours, but if they move towards each other they meet in 1 hour 40 minutes. Find the speeds of the cars.

When you are standstill holding a flag, the flag flutters in the direction of wind. When you start running the direction of fluttering of the flag changes to the direction of the wind relative to you. In all case a flag flutters in the direction of the wind relative to the flag. Winds is blowing uniformly due north everywhere with velocity 12 m/s. A car mounted with a flag starts running towards cast. after 9s from starts the flag flutters in 53^(@) north of west and after 16 s from the start the flag flutters in 37^(@) north of west. (a) Find velocity of the car 9 s after it starts. (b) Find velocity of the car 16 s after it starts. (c) If the car maintains uniform acceleration, find acceleration of the car.

Two wires A and B are of the same material their lengths are in the ratio 1 : 2 and the diameter are in the ratio 2 : 1. If they are pulled by the same force, their increase in length will be in the ratio ........
